That's been my impression too. The few folks I've spoken to who went through the upgrade all said the same. One the one hand I'd like to do an in-place upgrade because if it works I could be done in an hour or two. On the other hand if my experience follows that of others I've read about I could hit lots of snags and have all my DB monitoring down for an extended period. Potentially days.
Even though it's much more work I'm leaning towards installing a completely new OMS and repository on a new host and migrating each agent one at a time. It buys me the confidence of knowing that I'm still monitoring all my targets througout the migration, but I will undoubetly lose any historical metric data from the original repository, and will have hundreds of firewall rules that potentially need updating.
