Hei all,
we have a larger NAV setup with a bit more than 1000 Cisco Switches and use quite a lot of the features supported in NAV. Since our setup is a bit dusty we plan to upgrade (nav 4.9.5 on debian 8.11 to nav 5.3 ideally debian 11). I wanted to ask for your advice on the upgrade paths possible. We use a external db server that hosts the postgres db.
Requirements/Whishes:
- it would be great to keep the devices history and graphs so a simple
dump.py and reinstall would be a bit lossy
- it would be nice to start with a fresh installed debian 11.
Is there a good/preferred path that we could follow?
When we did the leap we also changed HW, so we were able to run the two versions in parallell and work out the kincks. We also have the carbon files on a separate server so all graphs were saved. Even if you run carbon on the NAV-server the data files should not be touched by a reinstall.
