This will save all user information, such as logins and profiles, +but will otherwise purge the database. This includes messages, which +rooms the home server was a member of and room alias mappings. + +If you would like to keep your history, please take a copy of your database +file and ask for help in #matrix:matrix.org. The upgrade process is, +unfortunately, non trivial and requires human intervention to resolve any +resutling conflicts during the upgrade process. + +Before running the command the homeserver should be first completely +shutdown. To run it, simply specify the location of the database, e.g.: + + ./database-prepare-for-0.5.0.sh "homeserver.db" + +Once this has successfully completed it will be safe to restart the +homeserver. You may notice that the homeserver takes a few seconds longer to +restart than usual as it reinitializes the database. + +On startup of the new version, users can either rejoin remote rooms using room +aliases or by being reinvited. Alternatively, if any other homeserver sends a +message to a room that the homeserver was previously in the local HS will +automatically rejoin the room. + Upgrading to v0.4.0 =================== |
