So just throwing this out there.
We are currently on 2016.3 SU3 (Soon to be SU5)
We plan to move to 2017.3 early next year.
Out current server and database has been upgrade a few times now and I am not convinced all is well with the database. (I have a call open with support who are going though the DB and have found inconsistencies)
What I was wondering was is it possible to do a nice clean install of 2017.3 and then just import certain data from the DB instead of the whole thing?
Users is not a problem as we use AD groups so it would be more inventory data, patch history, package data, etc.
Just a thought.
