information:

1. have our fsmo roles divided on 2 dc's.
2. server has schema master, operations master & infrastructure master
3. server b has rid & pdc
4. running exchange 2003 latest service pack
5. have citrix 4.0 on 2003 latest service pack.

questions / concerns:

2. want on 2008 r2, once have servers upgrade 2008, can r2 upgrade done without total upgrade scratch? since r2 64bit only, exchange have problems r2 or 2008 dc @ all?

hello,
please inline response

1- 1 of 2 fsmo roles should upgraded first? matter? 
 
  doesnot matter, advise transfer rid , pdc role (temporarily)from server b server a, inplace upgrade of server b after success, move 5 roles server b , inplace upgrade server , move fsmo roles where..this incase hardware or other failures might occur during upgrade.

2. want on 2008 r2, once have servers upgrade 2008, can r2 upgrade done without total upgrade scratch? since r2 64bit only, exchange have problems r2 or 2008 dc @ all?

this depend on current hardware..w2k8 r2 runs on 64bits, if current hardware not support 64 bit, need buy 64 bit system , clean install, if current hardware support 64 but, can inplace upgrade well.

exchange 2003 is not supported on 64 bit system. may have upgrade exchange 2007

on side note, remember run adprep /forestprep, adprep /domainprep on server before start inplace upgrade.

also, instead of inplace upgrade, may suggest clean install on both move roles 1 server , vice versa
