If you want to merge several individual Creately accounts to one Creately Team account there is no downtime involved. What you should do is:
- Decide who will be the account owner and responsible for the billing.
- That person should visit: http://creately.com/plans and pick the appropriate size team plan.
- Once they have subscribed they should visit: https://creately.com/account/team/manage and paste in the email addresses of the people who should be included in the new team plan.
- Each invited team member will receive an invite in their email with a link to confirm their invitation to join the team. Once confirmed they will be upgraded to the team plan and have access to all the features.
The diagrams that belonged to the individuals before they join the team plan will still be accessible and can then be shared with the team members and collaborated on.
