About Productivity Pak version 4.5

Hi folks

We are currently using version 4.51 (purchased through SAP) and are currently migrating our applications to a different data center.

Where can I find information on the list of supported databases and operating systems? e.g. Will this version work on Sql Sever 2012?
If not what is the impact of upgrading?

Also where can I support information like end of support dates etc?

FYI - I have already checked PAM and they only mention version 4.4. There is no mention of upgrades and even with that version, there is no mention of supported databases.

Can you please help?
