join existing sharepoint farm to new domain without trust

HI,

i need to make a case study on how to join my existing sharepoint farm to a new domain without trust.

=> without reinstalling the sharepoint 2010 farm.
=> what i want is to disjoin the servers from 1 domain and joint them to the new domain.
=> the same users will be present in the new domain (of course with other sids)
=> i have integrated security and forms servers with workflows, can i remap them using
stsadm -o migrateuser  ?
the farm consists of:
2 WFE
1 application server
1 database server
I read a lot of conflicting answers on the web.

thanks
