Can we perform a migration from Domino to Exchange or Office 365 with DAOS enabled?
Yes, Notes Migrator will process mail files that have DAOS enabled and will migrate attachments.
This may have an impact on migration throughput (speed) depending on the source Domino server processing and disk IO by the DAOS task.
The recommended options would be:
1. If you are using a Staging Domino server, then turn off DAOS on the Staging Server (not the production mail server) which will restore attachments to their original mail files with no further action required and reduce the DAOS overhead on processing time during migration.
2. If you are migrating directly from original Production Mail Servers, then DAOS can remain in place but Domino server performance should be monitored during migrations.
