Upgrading

1. Before you update any instance to 8.3, have a backup in place.
2. Now download the new core and present it to your instance (by symlink or copied files)
3. Use the install tool to run the upgrade wizards
4. Use the install tool to clear each and every cache you can find, even opcode.
5. When you encounter compatibility problems with your extensions, look for the git versions around in order to find one already upgraded. For example RealURL can be found here, until it gets released to TER: <https://github.com/helhum/realurl&gt;

The usual upgrading procedure applies as well.
