Planned maintenance due to table migration

In order to keep our codebase clean, we occasionally have to make large changes to it. This time we have to migrate all projects on all stacks to use the new code.
This is an internal change only. Afterwards, you will not notice anything different.

The migration will take place between January 17 and January 21, 2022. During the migration, we will disable all projects for a few seconds to convert the data.
All your configurations will remain intact, and your usage of production and development branches will be unchanged.
