I am curious to what other people experiences have been on how long it took them to go through all of the steps in the BSM Upgrade Wizard? It is taking a very long time to for us to go past the "Configuration Upgrade" step of the process.
Asking this question you will get a different reply from each person asked. After going through the upgrad process from bac to bsm a bunch of times now in different customer environments i can say that it has been different every time. Best case with a rather small deployment was approximately 48 hours with some minor fixing in the DB. Worst case was about 6 weeks with a ongoing support case and complex database problems. on a very high level i would recommend these things:
- run the pre upgrad tool and fix the issues. and i mean really fix them
- go thourgh the upgrade process on your test/integration environment. the test environment should be as similar as possible.
- DO NOT change anything on the DB side while working on the upgrade. means do not upgrade or patch the DB at the same time.
- make sure to have vaild backups for the DB and for the server (VMs).
Also i would recommend to read the documentation for the upgrade. Solid planning and documentation can be a big help here.
