Rolling upgrade question

Hello Community,

According #sec-ha-migration-upgrade-rolling we can migrate within one week, but is it the same for SLES 12 SP4 to SP5 ? According to the document , there is no mention for SP2 → SP3 (non-geo) or SP3 → SP4 (non-geo) either.

As per the document ,my understanding is that this limit is not valid for SP2-> SP3, SP3-> SP4
