To become the administrator of the existing account
The problem is: the webmaster has given me not full access to Analytics. He no longer works for our company. I can confirm the rights for the domain, but I don't understand how to give to the account, for which Analytics was collected for a year, the creator's permissions. I tried to create a new account, but a new account collects new data, but I need all the data from the account.
Thank you, if you can help me to solve this problem.
