I'd make sure you routing works between the two vlans - always fun finding
your server come up with a new IP address and then you, or one of the
servers providing license services, or database connections lose the
connection because a gateway address or subnet is not configured properly.
You might want to check any iis services/ica winstation service to make
sure
that no one has forced the service to look at a particular IP address
rather
than 'default'
If you've WI/PN agent/CSG services you'll need to update those as well
whenever you move a server that's referenced by them. Likewise for any
altaddr's you might have set up? Same goes for DNS entries - are they all
dynamically configured or have you got some specific cname entries that
have
been configured manually?
Possibly a check to make sure no bright spark configured a local hosts
table
entry on server(s) hard coding zDCs/license server/datastore?
Bear in mind that the clients are going to be referencing something - do
you
have hard coded references to servers, or do you have DNS names (e.g.
ica.mycompany.local) configured for your clients?
Once you've moved a server you could run a qfarm and a dscheck to make sure
there is nothing untoward hanging around.

Subject: [THIN] Server farm IP change - will it work?
Hi
I need to move all my servers onto a separate VLAN and therefore need to
change all the IP address's on all servers in the farm. Are there any
gotchas I should be aware of?
- Is there an order in which I should do this - ie data collector first? WI
server first?
- Has anyone encountered any issues changing IP's on all servers in a farm?
- Does Citrix use the IP address for any function or does it use server
names only?
- Will I need to recreate the LHC after changing IP's?
Farm is based on Presentation Server 4.
Thanks
Angela
