Hardware upgrade CoreXL issue

[nemezis_rock]

Hi mates,

Planning to upgrade from 6000-series to 9000-series without downtime. Two appliances of 6000-series in ClusterXL (HA-cluster).

Facing one prerequisite problem:

There is a prerequisite regarding coreXL count - they must be same number on both old and new hardware. But 9000 series doesnt allow me to change corexl instances count less than 10:

Illegal number of instances: 3 (should be between 10 and 20)

Did anyone faced such problem? Any solution?)

Your 9000s will have Dynamic Balancing enabled, and I think will just work it out for you. Worst case you may experience some connections having to re-establish - you'll know before there's any impact though, if the 9000 doesn't enter the Standby state and remains Ready or Down.
