Finally found a reliable IMAP/Office 365 migration utility that runs natively on Linux

I manage a mostly Linux-based infrastructure and have been struggling to find migration software that doesn't require spinning up a temporary Windows VM.

Most of the popular enterprise options are Windows-only executables. However, after testing a few scripts and Java-based options, I managed to get a full migration running directly on Ubuntu using a tool that specifically supports a generic Linux startup script (startup.sh).

For those of you looking for the Best Email Migration tool that actually supports the Linux ecosystem, this one handles:

Source/Destination mapping via CSV.

Delta migration (skipping duplicates).

Concurrent mailbox transfers.

It requires JRE to be installed, but otherwise, it’s a smooth process compared to using Wine or a VM.

Has anyone else here successfully migrated an Office 365 tenant using only Linux-native tools?
