- Build NewServer with W2K and all service packs and patches you need. This can be done well in advance.
- Stop all exchange services on OldServer and set SA to disabled (just in case something else tries to start it)
- Rename OldServer to OldServerXX
- Rename NewServer to OldServer and install Exchange including any connectors. Install correct Exchange service pack. Use PerfWiz to move files to the correct locations.
- Stop all Exchange services on New OldServer. Rename or delete all EDB's, all Log files and the Exchange .CHK file.
- Copy over the edbs (not logs or any other files) from the original server to the correct locations.
- Start the services. You will get error events telling you that it is rebuilding the indexes because of a new OS or service pack. When they are finished rebuilding you will get an error message telling you to run ISINTEG -PATCH. When that is run you are done. BUT dont forget to BACKUP straight away.
If all goes pear shaped then you still have the original server which you can rename back.
I have used this method many times and with a 150GB Priv.edb adn a 30GB Pub.edb the whole process took about 6hrs with nearly all the time taken copying the file.
