All.. I recently and unexpectedly stumbled across this in one production and thought it was an interesting one to document and share.
Upgrading CUC cluster from 11.0 to 11.5.1
When attempting to switch versions, I received the following error:
‘ERROR Sync after switch version failed’
Workaround (**For me!)
Make sure that the inactive version on the Subscriber node is the SAME (11.5.1.xxxx) as the inactive version on the Publisher. This resolved the issue for me! Hope this helps.
I just wanted to take a moment to provide an update, as I know things have gone quiet recently with regards to my vBlogs and general progress for the CCIE.
So the reason behind this radio silence is a good one.. I am delighted to have accepted a position with INE as ‘CCNP Collaboration Instructor’.
I was blown away when they offered me the position and for me this is a huge opportunity that I can’t wait to get stuck into and complete. At some point this year you will hopefully see the end product up and available on the INE website. I will be covering CIPTV1, CIPTV2, CTCOLLAB and CAPPS in the usual INE format.
So yes things will quiet down for me on this website, but I will be back don’t worry and fully intend to carry on and complete the CCIE Collaboration. 🙂
