Is successul upgrade from early pre rc1 19.07 branch to 21.02.0 expected?

Looks like I'm running a snapshot before v19.07.0-rc1. Can I expect successful upgrade with preserved configuration when upgrading to 21.02.0?

OpenWrt SNAPSHOT r10386-030d3f48e5 / LuCI Master (f138fc93)

personally, I'd upgrade in two steps ... to 19.07.x then to 21.02

I thought about that as well. However, I didn't check if the upgrade to 19.07.x is guaranteed either. Might you know?

The nbg6817 can be upgraded without problems, without intermediate steps. Keeping configurations isn't recommended between major versions, but should still mostly work in this case (still, not recommended).
