Migrate to 11.2.1

I don't think you can avoid downtime when migrating from v10 to v11 due to the changes in the failover topology from one version to the next. Even with serial failover I still think because v11 now has traffic groups it'll come up as Active by default and the v10 will also be Active. When I recently did this upgrade that was my understanding anyway.

 

 

I'd always plan for and schedule downtime anyway just in case.

 

 

As for your issue re the Config Sync - I had a similar issue and the resolution was to remove the one device reporting changes pending from the device group and then re-add it.

 

 

Hope this helps,
