I have a client who has recently changed there bordermanager server instead
of upgrading it to 3.8. they have done a vanilla install and then taken the
old 3.6 box out of the tree and installed the new one and given it the same
IP address but a different name.

My problem is they don't have any filters and when they try and add them
back through filtcfg FILTSRV.NLM abends.

Now my question is, can I rename the interfaces to match the old servers
interface and copy the filters.cfg file to the new box then run the migrate
into NDS.?

Also, what are the implications of renaming the interfaces?
