What it is good at
Two-way directory synchronisation means source and target coexist for months while you migrate in waves. Resource updating re-ACLs servers and workstations automatically, and you can roll a user back.
Where it falls down
Needs agents on domain controllers and a trust; licence cost is the main objection versus ADMT.
Capabilities
- SID history

Cost and licensing
- Cost category
- Paid — Commercial licence required.
- Indicative price
- Per-user perpetual or term licence, quote based
- Licence model
- Licensed per migrated user/account, perpetual or term, with separate maintenance.
- How to license it
- Quote from Quest or a Quest partner, sized on the number of enabled user accounts to migrate. Licence keys are applied in the Quest console. Ask about short-term project licences - AD migrations are finite and Quest will price a 12-month term.
