question to anyone who can help really, or who has experienced the same thing.
During the Server upgrade to v5.x the installation package says to wait whilst "making changes/updates to database".
What exactly does the schema changes entail.....It took a rather long time and the server was panicking a little bit towards the end....as were I :-)
If there is an easy explanation, would love to know. It would make my Change Management a whole lot happier if I can explain things for our Production Env.
