EV and Centera, switching to Compliance Plus Edition

Hi

This is a follow up to: http://www.symantec.com/connect/forums/ev-902-centera-questions

I would like to confirm the following.

If I switch our Centera from Governance Mode to Compliance Pus Edition but DO NOT change the partition properties (i.e. it's still set to Never) - does that mean that nothing changes in the way EV applies retention?

i.e. users will still be able to delete mailbox archived items as they currently do?

thanks!
