+Encryption migration
+====================
+
+Encryption format
+-----------------
+
+Nextcloud still supports the legacy encryption scheme used for server side encryption.
+However it is recommended to check if you have to still support this scheme.
+
+Starting with version 20 for new installations the legacy encryption will be off by default.
+However if you are upgrading there is a migration path to check if you can disable legacy encryption.
+
+Checking for old files
+^^^^^^^^^^^^^^^^^^^^^^
+
+On the command line run:
+
+ occ encryption:scan:legacy-format
+
+The command will tell you if you can remove the legacy encryption mode.
+If so remove the `encryption.legacy_format_support` from your config.php or set it to `false`.
