The first is to export and then import all the contact details and the second one is to simply share the contact details with complete ownership, without downloading or uploading any file.
In order to export contacts from your employee’s G Suite account, you need to reset the password from Google Admin first so you can log in to the user account. Once you have the access to the employee account, follow the steps below:
Go to Google Contacts and click on Export in the left side menu (third last option)
In the newly opened popup, choose the contacts you want to export and choose the option as per your desire and click “Export”
Now your contacts are easily exported. In order to import these contacts to another G Suite account, follow these steps.
Go to Google Contacts and click on Import in the left side menu (fourth last option)
In the newly opened popup, you need to click on “Select file” and select the file you have exported earlier. Then click on Import
All the contacts are now imported into your G Suite account. There is another way to take the ownership of all the contacts from any employee if they decide to leave the organization. You can simply install the chrome extension of Shared Contacts for Gmail and easily share your contacts with anyone with any permissions.
Once you have the extension installed, all you need to do is to follow these simple steps:
Hover over the label of which you want to take ownership
Click on the share button and add your email address in the newly opened popup and click on Share button
Now the popup screen will be redirected to the permissions screen where you can edit the permissions. Open the dropdown menu and click on Owner.
