Hi everyone,

I’ve been researching ways to move from Exchange 2019 to Office 365, and I found this detailed guide that explains all the methods, manual (cutover, staged, hybrid) as well as automated approaches:

Exchange 2019 to Office 365 Migration – Step by Step Guide

The blog also introduces the Shoviv Exchange Migration Tool, which looks like a solid option for handling large or bulk mailbox migrations. Some features that caught my attention:

  • Direct migration from Exchange 2010/2013/2016/2019 to Office 365
  • No downtime during the migration process
  • Delta migration to sync newly arrived items after the initial move
  • Supports batch mailbox migration without size limits
  • Preserves data integrity, folder hierarchy, and permissions
I’m curious to know from others here:

  • Has anyone already tried this tool for Exchange 2019 to Office 365 migration?
  • How was your experience compared to manual methods like PowerShell or Hybrid migration?
  • For large mailboxes (50GB+), what challenges did you face and how did you overcome them?
Looking forward to hearing your thoughts and real-world experiences.
