FQDN change with upgrade - impact?

[AdamD]

Good morning,

We are making plans to upgrade to V15 SP5 in the next few weeks. We are also planning to change the FQDN associated with our Web Admin portal as well as our provisioning URL using a wildcard cert. Beyond global DNS changes. are there any major "gotchas" to be aware of along the way?

I'm aware that phones will need to be reconfigured to point to the new provisioning URL. Is there anything anyone else can suggest to lookout for?

Thanks,
Adam

Hello @AdamD

From what version will you be upgrading from? It's a different procedure if you already are on V15 than coming from a version prior to V15.
Please advise
