What are the challenges of tenant-to-tenant mailbox migration?
People look for straightforward solutions for their migration needs. Ideally, migrations need to be rapid, smooth, and without any needless complexity acting as friction. Migration needs to just work without becoming its own thing.
Still, common challenges arise, especially when mailbox migrations come into the picture. Some common challenges include:
Challenge #1: Microsoft tools are complex
Here’s a common migration scenario: using Microsoft native tools like the cross-tenant mailbox migration tool, and realize they’re not particularly easy to use and often cause issues during migration, especially with large, complex migrations where limited features create migration issues.
The project stalls or fails, and then your IT team has to spend time trying to find a new solution. Add to this the fact that even Microsoft’s native migration solution for tenant-to-tenant migrations is a paid add-on, which just decreases the need to opt in for it versus a third-party solution.
Challenge #2: Staying on track with your timeline, budget, and business continuity
Migration projects happen fast and involve more than just moving mailboxes. Using different tools can make things take longer and add complexity. You want to aim for a smooth migration that stays on schedule, within budget, and keeps business rolling.
Most solutions on the market, including Microsoft native tools, are clunky and difficult to learn. This often leads to spending more time to ensure everything has been moved correctly rather than simply executing the migration.
Challenge #3: Licensing troubles
A common issue users face is the need to purchase a separate license as an additional add-on feature to migrate mailboxes. On top of that, the licensing models are quite complex and require some time to understand a suitable pricing model based on the amount of data that needs to be moved. And making mistakes might require more licenses, leading to budget overruns.
This escalates both cost and migration complexity. The more tools you use, the more problems and delays you’ll face, leading to higher migration costs.
