Few #migrate2vcsa VMworld sessions & HOL worth checking out

by // 4 Comments

One thing that I had noticed at VMworld last week was that there was a lot of excitement and buzz coming from our customers/partners around migrating from a Windows based vCenter Server to the vCenter Server Appliance (VCSA). I am pretty sure it had nothing to do with the awesome #migrate2vcsa stickers that my buddy Emad had created.

or the killer #migrate2vcsa apparel ...

In all seriousness, I do think our customers are genuinely excited about this upcoming migration capability and the value of the VCSA over the Windows vCenter Server. This is especially true for simplified lifecycle management from deployment (Day 0), configuration (Day 1), patching and upgrade (Day 2) of the VCSA. Customers not only benefit from the operational aspect of the VCSA, but it also allows them to reduce their overall Windows licensing footprint for both the vCenter Server as well as the backend database which is usually a Microsoft SQL Server or an Oracle Database. I do understand that this is not the goal of all customers, but I also know of many customers who do appreciate this additional CapEx savings.

At VMworld this year, there was a ton of coverage across a variety of topics for the VCSA including Migration, Deployment, Management, Operations and most dearest to my heart, Automation which spans all of these areas. I thought it would be useful to share some of the content in the form of publicly available VMworld sessions that you can view regardless if you attended VMworld or not. I know many of you have been asking about the VCSA Migration Tool and all I can say is check out the resources below and stay tune for an update real soon 😀

#migrate2vcsa HOL (simulation):

I just found out about this, but it looks like our Hands-On-Labs folks also built a nice VCSA Migration simulation HOL (http://docs.hol.vmware.com/hol-isim/HOL-2017/hol-1710-vcsamigration.htm) that you can try out which gives you a sneak peak at a Tech Preview of the VCSA Migration Tool. You simply follow the instructions to the right and it walks you through the simulation and highlighting what you need to perform via the orange colored icon. I thought this was a very neat solution for folks to get an idea of how something works without having to sit through hours of content. migrate2vcsa-hol

Lastly, here are some of the general vCenter Server / VCSA sessions that are also worth checking out.

Windows Server 2012 fix is out for the VCS to VCSA Migration Fling!

by //

Happy New Years everyone! Here is the first post of 2016 🙂

I know many of you have been anxiously waiting for a fix to the Winexe bug that causes the VCS to VCSA Migration Fling to fail when migrating from a vCenter Server that runs on Microsoft Windows Server 2012 (includes R2) OS to the VCSA. It has taken a bit longer than we all had hoped due to legal reviews and such, but today I am please to announce that we now have an updated release to the VCS to VCSA Migration appliance (v0.9.1). For customers using Windows Server 2012, WinRM will be used instead of Winexe due to the Windows bug that has been identified and will require a couple of additional configurations on the source Windows vCenter Server prior to starting the migration process. For more details, please refer to the documentation on the Fling site. Customers using Windows Server 2008, Winexe will continue to work as it does today.

In addition to this fix, we also now support specifying a custom port for the Microsoft SQL Server Database in case you had changed it from the default of 1433, which a few customers have asked for.

I would like to give a big thanks to both Mike and Ravi for working tirelessly on getting this fix out as soon as they could along with all the legal hurdles. Let us know if you have any feedback by either leaving a comment below or better yet, interact with the Engineers by leaving a comment on the Fling site!

Handy tidbits & workarounds for the VCS to VCSA Migration Fling

by //

The VCS (Windows VC) to VCSA Migration Fling has been out for a little over 6 months and the response from customers thus far has simply been phenomenal. We have also received some great feedback (200+ comments) from customers who have tried out the Fling in either a Dev/Test environment and some even in their production environment for those that are a bit more on the adventurous side. I have also had the pleasure in talking to some of these customers who have been successful in migrating off of their Windows vCenter Server (both large and small) and onto the vCenter Server Appliance (VCSA) and sharing additional feedback they may have about the Fling and how we can further improve.

Given the popularity of this topic, I thought it would be useful to aggregate some of the learning's, tidbits and workarounds that have been discovered in the past 6months to help any new or even existing users who might be interested in trying out the Fling. We really do appreciate all the feedback that everyone has given in the various forms and in fact, several of the workarounds were ones provided by our customers. As you know, the Fling today is not currently officially supported, however the feedback has really helped our PM/Engineering team. In fact, you can even get a sneak peak at an early Tech Preview we did at VMworld here to give you an idea on how some of your feedback has influenced a feature that may or may not be out in the near future 😉

Tidbit 1 Microsoft Windows 2012 is currently not supported.
Additional Info There is a known winexe bug which is affects migrating from this specific OS platform.
Workaround Engineering has a fix for this and is currently in the process of testing the fix along with legal review. There is not an ETA due to the review but we hope to release an update to Fling that includes this fix very soon. Stay tuned!This has been resolved with v0.9.1 of the Migration Appliance and for more details please take a look here.
Tidbit 2 Use of non-default (custom) ports on Microsoft SQL Server Database is not supported
Additional Info The Fling currently assumes the SQL Server Database is running on port 1433
Workaround Engineering has a fix for this and is currently in the process of testing the fix along with legal review. There is not an ETA due to the review but we hope to release an update to Fling that includes this fix very soon. Stay tuned!
Tidbit 3 Use of an Embedded Microsoft SQL Server or Microsoft SQL Express Database on the vCenter Server is not supported
Additional Info Since the source Windows vCenter Server must be powered off during the database migration; running the database on the same source vCenter Server is not possible.
Workaround One option is to re-ip the source Windows vCenter Server and ensuring the vCenter Server service is completely disable which would allow the Migration Appliance to communicate with the database. This is not ideal as you are modifying the source Windows vCenter Server but has worked in our testing. Second option that several other customers have recommended instead is to export the vCenter Server Database to a single instance of a Microsoft SQL Server or Microsoft SQL Express and that has worked really well.
Tidbit 4 Clustered database such as Microsoft Clustering Services (MSCS) is not supported
Additional Info There have been issues from some customers when trying to connect to an instance of the vCenter Server Database behind an MSCS Cluster.
Workaround Exporting the vCenter Server Database to a single instance of a Microsoft SQL Server or Microsoft SQL Express and then using the Fling has worked for several customers.
Tidbit 5 Issues connecting to a non-default named instance (e.g. SERVERNAME\VCENTER) of the vCenter Server Database.
Additional Info Some customers have had issues with the connection string to a non-default named instance of the vCenter Server Database during the database migration portion of the Fling.
Workaround A solution that was identified by a customer used the following: http://stackoverflow.com/a/11921896/2668394
Tidbit 6 Upgrade to VCSA 6.0 after migrating from Windows vCenter Server 5.5 to VCSA 5.5 fails
Additional Info You see the following error "Extra sequences: vpx_host_cnx_seq;" in /var/log/vmware/upgrade/vcdb_req.err during the upgrade to VCSA 6.0. These sequences are only found and valid in a Microsoft SQL Server Database and are not relevant in an vPostgres Database and just simply need to be dropped as they are not used at all.
Workaround Login to the VCSA 6.0 appliance as root and run the following command: /opt/vmware/vpostgres/current/bin/psql -U postgres -d VCDB -c "drop sequence if exists vpx_host_cnx_seq cascade"

If you are running into issues while through the the migration, one thing you can do is login to the Migration Appliance and go to another virtual console (ALT+F2) and view the Migration logs  under /var/log/migrate.log SSH is currently not installed by default. If you wish to pull out the logs for additional support, you can install which will require internet access and you can do so by running the following commands:

sudo apt-get -y update
sudo apt-get -y install openssh-server
sudo /etc/init.d/ssh start

The credentials to the Migration Appliance is vmware/vmware

Lastly, if there are other tidbits or workarounds that you would like to share, feel free to leave a comment and I will get it added to the list.
