Or as close to Zero as possible....
We have 2 sites, both using EXC 5.5 on 1 server. Seperated by about 800miles.
In a position now where i need to consider the impact of upgrading both
sites from 5.5 to 2003. Problem is, our Exchange server also takes care of a
number of other processes which we need to run 24/7 - this is demanded by our
client and written into a contract.
From what i read, to upgrade 5.5 to 2003 you need to build a 'swing server'
- we have no spares.
Can anyone tell me if there is an easier way to achieve this upgrade ? Is it
possible to do an inline upgrade going 5.5 to 2000 to 2003 ?
thanks in advance !!
