Is something missing here?

[FrancescoSer]

Not really, just preparing the section for later edits

[shanthanordic]

How about the old migrataion guides from cs to 2.7.0, should they all be removed as well.

How about the old migrataion guides from cs to 2.7.0, should they all be removed as well.

We should not remove them till the documentation is available for versions up to 2.7. There are direct links to those guides, removing the pages would break the old documentation. However, we could orphan old migration guides. @b-gent

please rereview

@carlescufi @shanthanordic Could you review this PR?

[miha-nordic]

Are we sure that Binaries bundle will not change for 2.9.0?
