Upgrading our mender enterprise server from 2.4.0 to 2.5.0 fails with:
"Failed to start up WiredTiger under any compatibility version. This may be due to an unsupported upgrade or downgrade."
It seems that mender 2.4.X uses mongodb version 3.6,
whereas mender 2.5.0 uses mongodb 4.4.
The update fails because according to mongodb docu, you must follow the upgrade path of
3.6-> 4.0 -> 4.2 -> 4.4 for mongodb.
We now upgraded to 2.4.1, but 2.5.0 still fails.
