I had a customer attempt this using the shell and it ended up taking forever due to a \

<div>We are planning to migrate from LDAP to AD, and one of the best solution was to \
change the uidNumber and gidNumber to what SSSD or Centrify would resolve.</div> \
<div> </div> <div>May I know, if anyone has come across a tool/tools that can \
change the uidNumbers and gidNumbers of billions of files efficiently and in a \
reliable manner?</div> <div>We could spend some time to write a custom script, but \
wanted to know if a tool already exists.</div> <div> </div>
<div>Please do let me know, if any one else has come across a similar situation, and \
the steps/tools used to resolve the same.</div> <div> </div>
