I've read the BKM but wondered if anyone had any advice from actually doing the upgrade as to whether to do
1) an in place upgrade
2) a fresh installation and reapply the database
3) a fresh install with a new database. just start from scratch basically
if 3 is a popular one is there a way to dump everything apart from the devices themselves? i don't want to lose the devices but am happy to rebuild queries, distribution packages, OSD scripts etc.
Any advice would be greatly appreciated.
