When to manually move the database

A manual copy may be required if you are having problems accessing the mail store. The problems are typically due to running Exchange before installing the correct service pack, causing Exchange to write to the database with an older version of the software that is not compatible with the newer database format. The workaround is to manually re-copy the mail store database after applying the service pack.
