It is best to keep your Nextcloud server upgraded regularly, and to install all point releases
and major releases without skipping any of them, as skipping releases increases the risk of
errors. Major releases are 9, 10, 11 and 12. Point releases are intermediate releases for each
major release. For example, 9.0.52 and 10.0.2 are point releases.

Please contact Tech and Me to help you with upgrading between major versions.
