simple question but is FIM 2010 suppose to be a replacement for MIIS 2003?

Yes, plus a lot more.Paul Adare CTO IdentIT Inc. ILM MVP

Fantastic!Ok to expand on this a bit more. Can FIM with the following:RACF (mainframe)Unix serversTrusted domains (two way trusts)People SoftLawsonFrom my reading so far I can see that there are alot of added features that allow users to manage Lists and stuff however is there a list of "out of the box" supported environments?Thanks!

What FIM does not have is any extra built-in MAs. The sync engine is basically a 64-bit version of MIIS. All the extras are in the new portal.There's always XMAs....http://www.wapshere.com/missmiis

Be aware, that the previous Host MA does not work with FIM 2010. So I am hoping to see some guidance on how to manage RACF/Mainframe, and Unix Servers out there. So while these existed in MIIS/ILM, they will not currently work with the FIM2010 Sync engine from what I've seen. I've been looking at using a dedicated ILM2007 environment to talk to the RACF, OS400 systems using the HOSTMA, and feed data to a middleman ADLDS instance which FIM Sync engine connects with. This is not a very ideal solution however. :(
