Forwarded Old Domain to New One, How to Login to Old Site's WP Admin?

Hello,

My company rebranded and so we have a new website. When we launched, I set the old domain (ocimageworks.com) to forward to the new one (occreates.com), but I’d still like to login to the old one. Of course, if I type in the WP login URL for the old one, I get redirected to login to the new one.

Any way to get into the old site while keeping the forwarding on? Though the new site is up and running, it’s still not quite finished, and I’d been using the old one for comparison and to retrieve files easier. I tried Wayback Machine, and the images don’t load on the pages I need to see.

We manage the domain ourselves, but the hosting is managed by another company so I don’t even have those details/access. I can change the hosting to an account we manage, if that helps, as long as this doesn’t screw up our emails.

(Sorry if this is a repeat. I’ve seen a ton of similar topics, but they didn’t seem quite the same as the issue I’m having and didn’t offer me any help.)

Thank you!
