External IP address change for UAG

All,

I will be changing the external IP addresses on my UAG.  I have seen articles/forum information that this isn't supported but that was based on SP1 and suggested full rebuild of UAG.  We are currently on UAG SP3.  I was thinking about taking the following steps.

• Change the External IP on the server.
• Reboot the server.
• Get into UAG GUI and running the wizard for Network Interfaces.
• Update/Check IP info for each of the trunks if necessary.
• Activate UAG.
• Verify objects/rules within TMG.

Any suggestions/gotchas would be appreciated.

Thanks.
