SAS Servers on windows need to be migrated

[vijayanand]

Hi,

We have a proposal to migrate the existing SAS platform from current Data Center to a new Data Center.  The current platform has 6 windows servers (2012 R2 and all virtaul) and these windows servers together have different SAS servers (batch server , metadata server,web server , Federation  Server , Data Flux , Visual Analytics  etc ) installed in them.

Is it possible to migrate them V2V (Virtual to Virtual). Does this approach have any down time for source .What are the pre-requisites , pros and cons.

Any information is helpful.

Thanks,

Vijayanand.

Copying the image to the new datacenter will take some time, so you will have downtime during that, if you need to preserve the whole state of the servers as they are at the moment.

But will you have the same servernames and IP adresses in the new location? From all my experience, I guess not. So it is better to set up a new environment and run both side-by-side until you have verified the new environment is functional.

BTW if you are not on the current version and maintenance level, this is a good opportunity to upgrade as well.

Check out the SAS support upgrade and migration resources: http://support.sas.com/software/updates/index.html

There are many things to consider when migrating and / or updating. As @Kurt_Bremser says, you may wish to use the opportunity to bring your software up to date and make other improvements. The above resources will help a lot.

You would need to copy the images while the SAS boxes are all powered down to ensure the images are consistent. When you boot them up on the new infrastructure the machines should have all the same configuration they had in the old vm hosts. Same NIC's, same MAC addresses, etc. If its all the same on the other end then it should all be fine. The tricky bit will be getting a consistent clone of the disk images without incurring too much downtime.
