7825 I4 shows supported with memory/HDD upgrades listed at the bottom of the link

License migration is discussed in detail here. Need partner access

Do keep in mind that 10.0 will be a virtual only release so 9.1 will be the last release to support MCS. If you don't move now you will have to make that jump eventually in 10.0 to virtual

Thanks Srini.

Just wanted to add that you will want to upgrade the memory and HDD before doing the upgrade to 9.1.
