Multisite after migration of wp site

Dear Team,

I migrate the site http://www.estheterra.com to a new server http://149.202.20.28/
When i try to set the site to Multisite, the site goes directly to http://www.estheterra.com instead going to http://149.202.20.28/
Any idea about the settings to modify to go to http://149.202.20.28/

Best regards
