Credit to redditor /u/jvinch76  https://www.reddit.com/user/jvinch76 for creating the basis for this modification.
I had been thinking of a script like his to keep my primary and secondary pihole raspberry pis in sync, but could not find the motivation to create it.
/u/jvinch76 did the heavy lifting and I made changes I hope you find useful.
 
I modified the code to increase the frequency of the sync to every 5 minutes and reduce the file writes by using rsync to compare the files and only transfer changes.
Furthermore, gravity will be updated and services restarted only if files are modified and a sync occurs.

1) Check logs in /var/log/unifi/ for clear errors
2) stop unifi service (systemctl stop unifi)
3) Potentially recover the crashed mongodb database (was crashed in my case) by starting it once from cmdline with a custom data directory (mongod --dbpath /var/lib/unifi/data/db). Then check the output of it to see if the DB was recovered. If it was, continue. If there was no problem, continue.
4) Connect to the database (mongo mongodb://127.0.0.1:27017( and run the following command:
db.adminCommand( { setFeatureCompatibilityVersion: "3.4" } )

That should give you the output
{ "ok" : 1 }

5) Stop the mongodb database
