+# Migration guide from Version 5.5 to 5.6
+
+This page contains steps that you might want to do when updating to 5.6.
+
+At minimum the server hosting webserver needs to be updated, but I suggest all servers are updated to the new version where possible.
+After update old versions will be unable to read/write web users.
+
+You can use `/plan servers` to check if you have all servers updated.
+
+## Setting up new web permission stuff
+
+This only applies if you have HTTPS enabled.
+
+The new web permission system is detailed here: https://github.com/plan-player-analytics/Plan/wiki/Web-permissions
+
+- Make one web user admin: `/plan setgroup {username} admin` (Needs `plan.setgroup.other` permission)
+- Go to `https://<plan webserver>/manage` and setup permissions to how you like them
+- Give your players `plan.webgroup.{groupname}` permission (eg `plan.webgroup.player`). This will ensure they can continue to register users.
+- Delete legacy_level_x web groups.
+
+Legacy group|Equivalent new default group|What they can roughly see
+--|--|--
+_didn't exist_|admin|everything + editing permissions
+legacy_level_0|read_all|read access to everything except /errors and /docs
+legacy_level_1|player_analyst|query, players and all player pages
+legacy_level_2|player|own player page
+legacy_level_100|no_access|nothing
+
+Moving users happens by deleting the group and selecting where to move the existing users:

+
+## Migrate Html customizations of old frontend
+
+Old frontend files are removed in 5.6 so old html customization no longer works. Migration guide: https://github.com/plan-player-analytics/Plan/wiki/Html-Customization--migration-guide-to-React
+
+## Fabric
+
+5.6 only supports Fabric 1.20.2 so you may need to update Fabric before updating.
