Does anyone know if this is a simple straight forward upgrade, by using the 4 files downloadable on CCO? It's to fix a known bug in 4.0 where the hard disk fills up but I can't find anything online except bigger jumps such as 3 -> 4.0(5) etc. The current versions are below!
O/S = Windows 2000 (5.0 build 2195 sp4)
SQL = SQL 2000 (8.00.760 sp3)
Exchange = Exchange 2000 build 4417 sp3 build 6.0.6249.0
Unity = Unity Voicemail 4.0(4.0) sr1
Server = MCS7815-I1-CC1/ECS1/IPC1
Upgrade to 4.1 and 4.2 should cost the same and if the customer has an SAS/SASU Contract it should be free since both these are minor/same 4.x upgrades.
