SharePoint Migration Tool calls are THROTTLED by O365 API
- Any updates on this topic?
No migration can be launched during the day since it starts to indicate errors like the following one:
MigSPTooManyRequestsException: Too many requests response from SharePoint Online.albegutWell, I might say, that we are in process of migration of an Intranet for one of our customers to M365, and it works good enough (in comparison to the time, when I started this thread). We were able to migrate 200 sites with average size from 100 MB to 1 GB.
Indeed, migrations work better in non-business hours and during the weekends. It's not so convenient, but at least it works - single migration session took from 30 minutes to 1,5 hours.
albegut There is nothing to update on this topic. The throttling is there to protect service quality during business hours of the region of the Office 365 tenant. You need to abide by the guidelines

The throttling is even more strict (lack of better term) due to the COVID19 situation. It is incorrect that you can not launch migrations. You can and it will migrate some content, but it will be throttled quicker in comparison to say if you start at 6 PM or weekend.
