Hi
I'm running two Cat 6880X-LE in a VSS Setup. Attached are a couple of Instant Access Clients.
Current Software Release is 15.1(2)SY4a.
According to the EFSU Compatibility Matrix in the Release Notes of 15.2(1)SY an Enhanced Fast Software Upgrade is not possible - (Incompatible)

My Question:
Do i have to do an ordinary VSS Upgrade (Fast Software Upgrade) - which means i will have a disruptive upgrade or is there anything i misunderstood?
Second Question:
If i do a Fast Software Upgrade, when will the instant switches be upgraded? After i upgraded the VSS Secondary or after i upgraded the VSS Primary?
I found some informations about the process with Enhanced Fast Software Upgrade but not about Fast Software Upgrade. Any Informations about that?
Thanks, Patrick
