Hi VGlassley,
It will not be a problem per say. You will need to make sure to update all references to IP addresses in your PlanetPress workflow. If you were using windows queues, then simply update your queues' IP addresses. You might have to go in the workflow and "re-select" each windows queue from each PlanetPress queue. If you were printing using a windows driver, then you will have to reselect each driver in each output task. Also note that in Version 6, you need all PlanetPress servers to be in the same subnet so they can see each other. For example, if your PPFax or PPImage softwares are installed on a different server than your PlanetPress Watch or PlanetPress Server, then they will still need to be on the same subnet.
I can't think of anything else.
Hope this helps.
Regards,
Olivier
