CUCM 8.6.2 to 10 Upgrade

Hi everyone,

Didn't have the following situation so far, so need advice:

I have an upgrade on the way, from CUCM 8.6.2 to CUCM 10, and that's fine,

But client needs to expand the cluster, by adding additional subscriber nodes.

Do I go with upgrade first, and then add more subscribers, afterwards?

or

Do I add subscribers first, and then do an upgrade?

Regards

you can opt for either of the ways

Hi Aman,Thank you for your

Hi Aman,

Thank you for your prompt response!

Can you give me the reason, why would you go with adding first, migrate later?

Since it doubles the effort. Is there any particular reason for the choice?

I personally would go with migration first, and add subs afterwards...

Are there any cons with my option?

Thank you again!

Hi ,

As such there are no pros and cons if u do with CUCM 8 first or 10 later on.

Personally speaking,It is more of comfort and command while upgrading on CUCM 8 first.
