If a migration takes a very long time, what can be the cause, and how can we investigate and mitigate the problem if there is any?
What is considered too long for a migration of an element?

The cause can be due to a variety of reasons.
The migration feature uses DELT, so the same reasons a DELT export can take a long time apply here.
Off the top of my head:
- Lots of data (alarms, trending, elementdata) in the database that needs to be moved.
- Lots of properties that need to be transferred.
- (Partial) inclusion in a lot of other objects (services, redundancy groups,...) that need to be updated.
Perhaps taking a DELT export could give some insight in why an element takes a long time. Both the UI and Skyline DataMiner\Logging\SLDELT.txt might show something useful.
