Depends on how you are upgrading.
If you are reusing the DB, then you are OK. If you are not, you need to use the migration steps that bring the configuration over.
1. I have extended the FIM portal schema to add new objects and attributes, will this cause an upgrade issue?
---No Issues. The customizations are on the DB.
2. I've automated run profiles using scheduled tasks and scripts, these scripts reference GUIDs on the sync server - presumably I need to
amend these scripts?
---Double check, but not a big deal.
3. I have customised the FIM portal, presumably I'll need to customise the portal again?
----All in the DB, not an issue
4. Is MIM compatible with existing FIM client plugins? We're using the SSPR plugin.
---Not sure 100%, but I am certain it is.
