The following is considered "best practice" for a staged migration with source and target Exchange organizations that have multiple sites:

1. Identify what site will be the last site to be migrated in your entire migration plan.
   
2. Create a project for each site.
   
3. For the identified last site ONLY (from step 1 above):  Use the TWOWAY direction for the Direction switch in the EMCLI DIRSYNC command.
   
• This will allow any new mailboxes that are created in the target to be accessible from the mailboxes still on the source.
• The source Organizations directory replication service will propagate the source CR that is created in the source to all sites in the source.
• Although not required, this will allow you to decommission each site when the migration is complete for that site.
  
4. For all other sites: Use the SOURCETOTARGET direction for the Direction switch in the EMCLI DIRSYNC command.
   
5. Continue following the steps in the following Knowledge Base article:
