You must export and import existed site to new blank site, if you want to move it to new site collection:

1. Export the subsite using the Export-SPWeb http://webapp/sites/subsite1 -Path "subsite1_export.cmp"
2. Create a subsite on the destination without template New-SPWeb http://webapp2/sitecoll/subweb2
3. Import site from exported file Import-SPWeb http://webapp2/sitecoll/subweb2 -Path subsite1_export.cmp -IncludeUserSecurity -Overwrite
