Warning - upgrade from 5.2.2.0.1562 to 6.1.0.0.935 breaks cluster

Dear Ruckus Crowd,

please be careful when you try to upgrade from 5.2.2.0.1562 aka MR2 release to 6.1.0.0.935. 

it might break your cluster and you will have a bad day if you do not have a exported cluster backup or snapshot.

Reproduced with vSZ-E. Testing other models tomorrow.

Setup clean vSZ with 5.2.2.0.1562 or upgrade one to 5.2.2.0.1562. Than make a backup and upgrade to 6.1.0.0.935. Upgrade process will fail after migrating database in step preparing system with cluster operation failed.

You will be able to get access to UI but after restart no cluster process will start any more..

More details will follow. 

Best regard,

Mark

PS: kudos to my colleague who found that out the hard way.. because APs for project changed to R350s and he needed to upgrade…

Hi Mark,

I have replicated this issue in the lab as well and had a quick discussion with the engineering on this issue. As per engineering the 5.2.2.0.1562 to 6.1.0.0.935 is not a supported upgrade path as the release the 5.2.2.0.1562 MR2 was targeted for 6.1.1(Releasing in next couple of months). The 5.2.2.0.1562 MR2 have changes in the database and binaries as per v/SZ 6.1.1, moreover 5.2.2MR2 have major bug fixes which cannot be ported to 6.1 which was released back in Dec 2021. The Supported upgrade path from v/SZ 5.2.2 to 6.1 will be 5.2.2.0.317 >> 6.1.0.0.935 or 5.2.2.0.1161 >> 6.1.0.0.935.

We acknowledge that we need to update the 6.1 Release notes with the correct upgrade path limitations and I have notified our Technical Publications Team to make this change at the earliest. Once again, thank you for bringing this issue to our attention through forums and we sincerely apologize for the inconvenience caused to you.

Regards,
Ankush
