Does migrating to a different email provider reset reputation?

I have a few domains I use for cold emailing on Google Workspace and planning to migrate to Office 365 as it is giving us better results, if I moved my already warmed up domains/emails from Google to another email provider will it affect the reputation of the email/domain?
And will we need to reset the warmup process again from the beginning?

Simple. You will keep your gmail account active for all of your registrations, but move anything important over to your new provider.
I turned on vacation mode, and have an auto response that I'm not using the gmail account anymore. You could try and auto forward your mail for a while, but you will want to stop this eventually.
I also use a password manager that also keeps track of my log-ins. If something is really important, I take the time to change my contact info. If it isn't I don't worry about it.

If your using same domains nothing to worry your reputation wont reset until 30 to 40 days. For safer side always do short warmups

Cheers
