Jabber migration from ISP1 to ISP2

[nuinoahmed]

Hello,

Any one already did such jabber migration from One ISP to another?  What and how did you achieve this?

Customer have one domain on ISP1.  And I would like to use the same domain on ISP2. 

there will be new CUCM, IMP, Expressway server.  With new hostnames, ip addresses,... 

Is it possible or is there a way to keep the same domain during the migration giving the fact that not all sites (all jabber users) will be migrated by location and this my take sometime to have all locations migrated from ISP1 to ISP2?

Thanks.

Your questions doesn’t really make sense. Are you referring to the public IPv4 address of Expressway-E for Mobile and Remote Access or something else? The ISP shouldn’t be involved in your corporate DNS domain name so mentioning domain is confusing.

If it’s the public IP of Expressway it can be as simple as changing the ISPs, updating the firewall config, update the NAT address on NIC2 of Expressway, and change your Expressway-E public DNS A record resolution.
