G Suite will move all contacts to new Google Contacts and shut down the present Google Contact on 12th Feb 2019.
If you are presently using Google Contacts, here is an update for you!
G Suite will move all the contacts in present Google Contacts to the new one (known as “Contacts preview”) and then will shut down the present Google Contacts which all of these are going to take place within February 2019.
Here are processes which will be taken place before the new Google Contacts will be in use, importantly only admins have to inform their users about new Google Contacts.
On 28th November 2018, admin can choose to enable New Contacts for users in Admin Console.
• If enabled, the default setting for users would be New Contacts but they could revert back to the old version
• If disabled, the default setting for users would be Old Contacts but they could manually choose to use the new version
After that on 15th January 2019, New Google Contacts will automatically be default setting for users but the users still can revert to the old version. And the enable setting on Admin Console will be removed as well.
And then on 12th February 2019, New Google Contacts will be default setting for all users and the old one will be shut down.
