Welcome to the Q&A Forum

Thank you for your answer,  yes we moved from www.example.com to
uk.example.com and the new countries will have 
us.example.com

now since all old links were for the www.example.com UK we are thinking of using the  change of address in Search Console.

Thank you for your answer: we did a 301 but I was considering the "change of address tool" to make sure we don't lose any backlinks.

Hi guys

So we had a domain that was only for one country, www.example.com

1 year later we decided to go to another country so we will have all the current website under a country subdomain like : ae.example.com

we did a 301 redirect
Should I perform a change of address action from www.example.com to ae.example.com  ?

please help
Thanks
