Allow new schema versions without having to update the schema #1024

Open AndrewSisley opened 1 year ago

Part of #1002

Not all version changes involve schema changes, sometimes only the data contained within needs to be changed. We should allow the system to handle this (including the migration system, Lens).

Note: This ticket is highly unlikely to be part of Defra v0.5 but will be tagged as such for now and then descoped if/when required.

This is at least partially tested by TestSchemaUpdatesMoveCollectionDoesNothing, but we could have more (perhaps an empty patch test for example, which should be added anyway). Will leave ticket open and as part of 0.5 for now

I misread the ticket. Moving to 0.6
