After restoring and upgrading the cemdb to 10.7.0.45, I upgraded the EM to the same version and started it. However, the EM failed to start with the following error:
[ERROR] [main] [Apm.Data.Model] APM Database is not reachable.

Upon further troubleshooting, we found out that the cemdb was actually empty. The restore process did not complete properly.
CA Application Performance Management 10.7.0.45
Re-run the restore process with the 10.7 dbrestore-postgres.sh script, which restores and upgrade the schemas to 10.7 successfully.
