Why You Might Need Accounts Merging in Google Workspace

The need of merging accounts in Google Workspace may turn up when your organization has multiple brands and you eventually want to merge everything into the parent company. Another possible scenario may occur when your organization acquires another company and there is a requirement to establish a unified workspace for the existing and new users. 

How to Merge Domains in Google Admin Console

The process of merging domains requires preparation and a well-thought-out plan. The thing is that Google Workspace doesn’t have a comprehensive functionality for accounts merging and deduplication. In turn, it provides several consolidation and migration options for the core Google services, such as Gmail, Drive, Google Calendar, etc. 

Thus, to merge two accounts into one there is no better way than exporting and importing data from each service separately. Once the data is successfully transported into a single account, the duplicate account can be deleted or archived.
