Thanks Shivaram,
we have existing contract with HP so we should be able to then upgrade to new version.
However, based on various views in this forum - advise to upgrade from 9.0 to 11.0/11.5 is to install 11.0/11.5 on different server.
If we install 11.0 on different server - would we be allowed to have 9.0 and 11.0 running simultaneously while the migration completes or is it as suggested by sdsded that we need to divide license between 9.0 and 11.0
for e.g. if we have license for 25 then allocate 9.0 - 15 and 10 for 11.0. not sure how that would be done will HP provides new license keys?
Regards, Raul
