We're currently preparing an enterprise email migration project that involves moving Outlook PST archives into Google Workspace. Most employees have accumulated multiple PST files over the years, and several departments maintain shared archives containing important customer communications. Since the migration affects business-critical information, preserving every email, attachment, folder, and contact is a top priority. We're also trying to reduce manual effort because validating hundreds of mailboxes individually would take weeks.

During the planning phase, I've been exploring different methods to import PST to Google Workspace, but each option seems to have advantages and disadvantages. Native utilities appear suitable for smaller migrations, but I'm not sure how well they'll perform with hundreds of large PST files. Our ideal solution would support batch migration, detailed reporting, mailbox preview, selective migration, and duplicate handling so we can complete the project with minimal post-migration cleanup. Pilot testing is already planned, but we're still looking for recommendations from organizations that have completed similar migrations.

While researching available migration software, I came across the DRS Softech PST to Google Workspace Migration Tool. It appears to include enterprise-focused capabilities like JSON authentication, advanced filters, mailbox preview, and batch processing. Those features seem relevant for our environment, but I'd value real implementation experiences much more than marketing material. Knowing what worked well—and what didn't—would help us avoid common mistakes during production deployment.

For organizations that recently had to Migrate PST File to Google Workspace, what lessons did you learn during the project? Were there any unexpected issues with large mailbox sizes, migration performance, or post-migration verification? I'd appreciate any best practices, checklists, or recommendations that could help make our migration smoother and reduce downtime for employees.
