Switching IPs on an aged account

[goblues]

I have a couple of accounts that I'm actively selling on (one created in 2006 and selling since 2017 and the other created and selling since November 2018 both doing >500$ sales daily).

I want to move them to a Dedicated IP that can be accessed by VA's and myself. I travel often so I don't want to risk the accounts bringing any suspicious flags by changing IPs (I travel to several countries in short periods of time so I could see how this could be possibly problematic).

My main question: Would it be safe to move both of these accounts onto Multilogin App (multilogin.com) and stick a Residential Proxy on each? Is this a sound plan? Should I anticipate any issues?

Thanks in advance.
