The migration was carried out in four stages
Astra Group and Pragmatic Tools tested the possibility of migrating Microsoft Active Directory corporate infrastructure to the domestic directory service ALD Pro. Tests showed that a domain migration of almost 300,000 accounts can be completed within a single overnight maintenance window.

The testing was conducted on the stand of a large Russian IT integrator. Pragmatic Tools Migrator was used for the transfer, and the components of the target domain ran on a virtual machine with eight CPUs and 16 GB of RAM.
Creating 296,000 accounts took 3 hours and 20 minutes, and 300,000 groups took 1 hour and 33 minutes. Specialists also transferred information about user membership in groups. The processing speed of accounts decreased by about 13% by the end of the test, while the performance of other operations remained stable.
During the first run, 19 accounts and 95 groups could not be created. A second run processed only the missing objects and corrected all errors in a few seconds. As a result, migration completeness reached 100%.
Pragmatic Tools noted that Migrator supports restarting the process without re-transferring already processed data. According to Astra Group's assessment, the test results confirm the possibility of switching to ALD Pro without multi-day downtime. Moreover, using more powerful equipment can further reduce migration time.
