SAS Platform Migration

[vijayanand]

Hi,

I am currently doing the pre study of migrating a SAS platform which is set up in WINDOWS(2012 R2) to WINDOWS (2012 R2) itself but in a different data centre. It has a BI setup (metadata server , webserver) as well.

As the OS is same , can I assume that 

Whatever the SAS code running in source would be running in target as well with out any errors.

Metadata can be exported from SMC and import it in the target platform.

Data in the source can as such be migrated on to target

Any other points that I should consider.

Thanks,

Vijayanand.

What SAS versions are you migrating from, and migrating to? If these are different then the SAS Upgrade page is a great resource:

http://support.sas.com/software/updates/index.html

For the migration part check out the Migration Focus Area: http://support.sas.com/rnd/migration/

Don't assume your code will run without error on your target platform - always test it. That is true whether or not you are changing SAS versions or OS's. It is pretty common to have something different or left out so your migrated code fails. Only by running your code will you know your target system is good. I would also advise comparing source and target datasets, at least the ones you have run code on, as well to confirm they are the same (PROC COMPARE is great for this).

Thanks for the quick response.

The SAS version remains the same on both source and target platforms (it is 9.4). 

I agree that TESTING should happen  and it takes a major role in deciding that the migration is successful.

My question earlier was, should I make any changes in the code post migration, before testing (i'm sure we would come to know in testing  whatever is missed out). However , would like to document the changes before hand.

Thanks,

Vijayanand.

Watch out for hardcoded values such as pathnames.

If you are upgrading to a newer maintenance release of SAS 9.4, then see SAS® 9.4 Guide to Software Updates.

There is no harm in running your migrated code unchanged to identify where there are any problems.

Just to be sure: 64 bits SAS to 64 bits?

Otherwise you'll have issues.

IF the OS and the SAS versions and the paths are the same, there is no change to make a priori. If not, you need to modify the code to cater for the known changes.
