we have a BES 4.3 i believe and are upgrading to BES 5.
what are best practices?
I am thinking a brand new vm machine, install the upgrade (if possible without ver 4.3 -- or do i need ver 4 on it first???)..
and migrate users slowly rather than upgrade the current BES and things might break.
this is done for exchange 2010 upgrade....
any suggestions or whitepaper i can follow?
thank you plenty :)
in that case, do I need to create a new besadmin account to authenticate the new BES install while the other bes is running?
