If I were you

Then upload the backup sql and the files to the server
Then create a new site (DNS multitenent on)
Point the A record to the new server IP
Then migrate site based on this database backup and unzip the public and private files.
Delete all email account and domain. Then reconfigure the email domain and mails

thank @Riyas_Rawther you for your answer.

because of some customization’s i really hope there is also a way to update just the site domain-path without setting up all new. also because the instance is already up and running with the new sub domain just erpnext is taking the old domain for mail service. also when i use sendgrid, the beginning of the links point to the old domain.

any ideas?

I think you can do this just changing some of the text files in your new site in frappe bench ie currentsite.txt and rebuilding your bench setup via ‘bench setup’
