Move to an other domain

[hpcrazy]

I just had a talk with my SEO expert and he made me the following suggestion which I want to make sure that this is possible :

I am running my board with quit a lot of paying members ( automatic renewal on PayPal ) on this domain here : https://www.hanspeterkruesi.com/members

but I would like to move the whole system to hpcrazy.com/members

So here the question :

Is it possible that I move all files to the new domain but also leave the files on the old domain but switch the old domain to " redirect " so that no user, paypal subscription or backlink get's lost. But any new content or registration would be made on the new domain.

Thanks for your help in forward.

I would do it it the other way around, redirect the new one to the old one, that way nothing changes.

My SEO expert gave me the advice to proceed that way. The 2 domains exist quit a long while but one " hpcrazy " is treated as a brand by google - and like 99% of the users come over " hpcrazy " there. So it make's total sense but I don't know what will happen with the clients who are on automatic subscription renewal.

So that's why I am asking here - if anybody has experience on that.
