I know this is a beaten question but everytime I start reading all the previous posts on this subject I become more confused :-) so here's what I got.
I’m looking at migrating our Unifi Controller 5.5.20 to another server. I found this great “How To” https://help.ubnt.com/hc/en-us/articles/115002869188input_string=migration+now+connected+%28migrated%29
but have some questions before I do this.
- I have three sites on three different subnets in physically different buildings/locations. I take it I will follow the instructions for all three sites, exporting, importing, and forgetting, then on to the next site. Will being on different subnets be a problem?
- On the new controller, should I restore the actual controller backup before I start importing sites? I want as little data brought over from the old controller, just configuration settings.
- I do have a DNS entry for “unfi” which points to the old controllers IP address. Should I change this to point to the new controllers IP address before I start the migration or after. I’m assuming I want to do this before because in step 8 it asks to put in the URL for the new controller and if I have the DNS already changed I can put in http://unifi for the URL leaving the :8080 and /inform fields alone. Unfortunately it looks like the “set-inform” was configured to the IP address of the old controller and not the “unfi” DNS entry.
Note that I cannot keep the same IP address for the controller. The server that hosts the old controller has other services running on it.
Thanks for your input
