Robert, I went through this exercise in the late 90's, so memory is sketchy at best. Here's some points that I remember:
Conversion method depends on how comfortable you are with changing and testing the TCP apps. You may be able to switch apps from one stack to another for testing successfully one at a time, but you still may run into snags at full cutover time when Interlink is no longer there. You might consider setting up a test window on a weekend or perhaps a test system, where z/OS is brought up with IBM's TCPIP in place and no trace of Interlink/CA. Then shake out each of the apps and decide when to cut over. Seems like IBM products and programs were generally better behaved than ISV products. At the time there were some functions that were supported on one stack but not the other, that caused us problems (IUCV perhaps?) In converting FTP control statements, Interlink ignored cc73-80, IBM's did not. Sequence numbers on control statements would be interpreted by IBM FTP as port number, causing misleading errors such as connection timed out, or invalid port.
