I will be migrating a NW60sp5 server to OES 65sp6. Migration rule is that
they both be on the same lan segment. We have a private network, the
source is 10.11.55.x and the destination is 10.11.50.x
Will this be a problem?

The soure has a dns name so i can't change it. And there are no available
IPs same as the source.

Please advice.
