Re: Upgrade & possible downgrade questions.

Hi Farren,

Downgarding? You cant if you dont have an DB backup that was taken in the 
earlier format, 5.1.6.2.
I´m not so sure what you are trying to do but...in short. Do:

Solaris 7, 5.1.6.2
Migrate all data from disk stgpools and backup DB.
Halt
Restore Db to the new server, Solaris 9, 5.1.6.2
Connect libraries etc.
Define new disk stgpools
Verfy and test.
If not OK fall back to the old solution.
If OK
Next week, upgrade to Solaris 9, 5.2.2.7

And yes, format new volumes before you restore your DB.

Secondly, dont do everything att the same time ie upgrade TSM and change your 
hardware.

Hi all

This Saturday I will finally be moving from an on Solaris 7 server (TSM
5.1.6.2) to a new Solaris 9 (TSM 5.2.2.7) one.

My question this time regards downgrading from 5.2.2.7 to 5.1.6.2 should I need 
to. Do I need to physically remove any existing dB and log volumes as well as 
un-install the software and then re-format them? Or, once I have installed 
5.1.6.2 again, can I just issue a dsmserv restore db command and it will 
happily use the space previously used by 5.2.2.7? >From the documentation it 
says to 'Reinitialize any database and recovery log volumes ' which I'm 
assuming means to remove and reformat.

Thanks

Farren
