Upgrade old backpacks to MC 1.13 and newer

With the release of Minecraft 1.13, the storage format has been changed significantly, this results in lost items if a backpack created with an older version is opened with MC 1.13 (or newer). This page will describe you how to properly upgrade your backpacks to the new format.

Requirements:

• Minepacks V1.18 or newer (but not V2.x)
• Bukkit/Spigot for MC 1.12.2 or older (only fully tested with 1.12.2)

Steps (Minepacks V1.18):

1. Backup you database!!!
2. Start your server
3. Use the "/backpack rewrite" command (Permission: backpack.rewrite). The plugin will not be usable while the command is running. Depending on the amount of backpacks it might take some time to complete.
4. Wait till it's done
5. Stop the server
6. Update to MC 1.13 or newer

Steps (Minepacks V1.19):

1. Start your server
2. Wait till the plugin is fully loaded
