Ask HN: How to migrate from LineageOS 22.1 to 22.2

[sterness]

I was working on LineageOS 22.1 source code, LineageOS released 22.2 version for the supported devices. All my work is still on LineageOS 22.1 version. How can I migrate all the source code from 22.1 to 22.2?

Is this possible with a repo command?
