Why would u even think of running it on such a old TMOS version.... :).....atleast bring it to 10.2.3.
May be what I am understanding from you comment is that you have old boxes which has less than 1G memory so in any case 10.x.x version will never get installed ... so you may have to stuck with 9.x.x try to get it sort out with some xtra investment.. :)...
If you use the manual configuration tables and instructions in the most-recent guide for BIG-IP version 10.x, you should be able to get most things to work without modification (caveat: we haven't tested that). Offhand the only thing I can suggest is that you probably shouldn't implement OneConnect profiles on v9.x because of various NTLM issues; you'll have to adjust the iRules accordingly to remove the OneConnect and NTLM references. There *may* be some other subtle iRule syntax that'll need to change, though offhand I can't think of any of the commands that have changed appreciably that we use for Exchange. That should be about it.
Good luck and let us know if you run into problems.
The white paper for BIP version 10.x Appendix A (Manual Configuration) has all the pertinent information needed to configure for version 9.3.1.
The monitor for port 135 is still something I need to work out as RPC is used for more than Exchange on the servers but configuring three virtual servers with three pools and the necessary adjustments for persistence and such works out fine.
