I have a site that I want to migrate from one domain to another, the domain I want to migrate my site to currently has an existing site of mine on it.
For the sake of this question let's call the current domain
example1.com, and the migration domain
Weighing up the risks involved in the migration, I have found that the
example1.com has a domain authority of 30 while
example2.com has an authority of 15. I have got these metrics from Moz's MozBar tool.
So my questions are:
On migrating these domains, is this likely to cause a drop in rankings?
If I point both domains at the same site, with
example2.com being the primary domain, will the authority from
example1.com be passed on to
