Hello Community,

According [#sec-ha-migration-upgrade-rolling](https://documentation.suse.com/sle-ha/12-SP4/single-html/SLE-HA-guide/#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
