First here is our current setup:

Software    Version           AIX OS            Client Level
Server Level
Informix          7.30.uc7    4.3.3       3.1.0.6                 4.1.3
Oracle            8.1.6.4           4.3.3       4.2.2.1
4.1.3
            8.1.7       4.3.3       4.2.2.1                 4.1.3

We need to upgrade the server to v5.1.x.  With the level of clients (and
API) we have:

1.  Can we still run the client levels we currently run until testing of
the new clients are complete, if we upgrade to the v5.1 server first.
2.  Is it required to go through the TDP with the v5.1 server?

Basically, if we upgrade our server to v5.1.  Will we need to do anything
with the clients we are currently using.  Will we need to add TDP?

I would like to be able to say, that they do not need to change anything as
of yet.

Thanks for any help you can provide!
