Hi,
My requirement is to migrate the sas applications currently running on AIX 7.1 to Linux. What are the pre requisites and salient features/aspects that I should look into, to devise the migration strategy/approach. The current application produces some reports on the BI platform.
Current SAS version is 9.3 and the target SAS version is 9.4
Thanks,
Vijay.
You might/will have to deal with big endian/little endian issues. Catalogs most probably will need to be migrated (export to cport and import from that).
Your big advantage is the fact that you will have two separate systems where the old platform is still operative until you are certain that the new one works. Much better than when you do a migration in place.
Consider to not migrate the metadata, but do a new setup, if you have lots of issues where things could be done better, but where the need for service continuity has prevented you to make a change.
HI ,
one more question regarding the application migration.
Source -- AIX and SAS version is 9.4
Target -- Linux and SAS version is 9.4
Both source and target are 64 bit operating systems.
What should I majorly look into for this migration, with respect to
Database connectors
SAS datasets
SAS catalogs
Flat files
Thanks,
Vijayanand.
Catalogs will most probably need migration. It's best to recreate them from the original code.
Datasets can probably stay, but if you see messages about CEDA (cross-environment data access), you might want to migrate them if you experience performance issues. Test with an un-migrated dataset first, then migrate it, then see if your code runs (noticeably) faster.
Flat files might need to be read with an encoding option, depending on the encoding setting on your new platform.
Can't tell you anything about database connectors, as we don't use them.
