I wish to change my primary domain to my new purchased domain (currently added as addon domain).
i have read the article in godaddy help : https://id.godaddy.com/help/change-your-accounts-domain-8344
but what I am worried is, will change primary domain cause lost primary domain's email account and email data or addon domain's email and email data. will those data deleted? if yes how to backup and restore? is there anyway to solve this case?
i think godaddy offer to move all of your data over for a reasonable fee. Speak with support or if you prefer do it yourself , but yes, backup all of your data.
