   You can perform the migration with the following three methods.

   1. Migrate Enterprise Vault to Office 365 with Azure AzCopy
   2. Migrate the PST file from Google Vault to Office 365 with EdbMails

   Migrating from Enterprise Vault to Office 365 is possible by exporting the PST files from the Export Archive Wizard in Enterprise Vault and then uploading the PST files to Microsoft 365 with Azure AzCopy tool. The second approach is to use EdbMails to migrate the PST file to Office 365. Let's go over the procedure step by step by using both the methods.

     • Step 1: Login as an administrator and open the Enterprise Vault admin console
     • Step 2: Right click on the Archives and select Export to open the Export Wizard

     • Step 4: Select the archive and choose to export all of them or based on the date range
     • Step 5: Browse the folder path on your computer to save the archive as a PST file
     • Step 6: Use Azure AzCopy to import the PST to Office 365 by using the network upload
