I’m really looking for some advice here in regards to an IP Migration that we have got to do in the near future.
We are currently using our Datacentres own IP Block however as we grow we want to create a bit more ‘independance’ etc, so we have been assigned our own IP Block for use with our servers.
Currently we have two Iworx boxes with this supplier that we wish to migrate to this new box, however it has to be done in one shot as apparently the machine cannot use both sets of the (old) IP Addresses and (new) IP Addresses at the same time.
Now, on ServerA (for ex) we have around 150 domains, with about 15 SSL Certs, ServerB around 50 domains and about 3 SSL Certs. I mention the SSL Certs because obviuosly these sites run their own dedicated IP and there is more config in the virtualhostname.conf file.
One of my questions is; when using the ‘Allow IP Changes’ button in the Edit Screen of Nodeworx, will this also automtacially change the IP Address that the SSL Cert is bound to? Anybody noticed any issues?
As we have to make the switch in one go - would you suggest reducing the TTL’s on the domains down to (something low) maybe 24 hours before?
Just really looking for some advice from anyone that may have had to do something similar
