Move Old Urls to New Site?

[chainazo]

I am not an SEO specialist or anything IT, I have a business selling leather products, that is why I ask this question: a while ago Google deindexed my website due to problems that I already solved, but I never re-uploaded the website or sent anything to Search Console to "notify" you that it was already fixed, because I would prefer to do the following if possible:

Make a "castling" of site names: suppose my site was ShoesBrand.com (let's call it Web A, with 25 years of registration, very well positioned locally until deindexing) and it had a total of 8 pages with certain content (texts, photos and videos all my own, nothing generic).

If I now want to move exactly those 8 pages with exactly the same content and the same design but to a new site LeatherBrand.com (Web B, registered yesterday) and to the previous site ShoesBrand.com I make absolutely new content...

Would Google penalize a website that has a new url (Web B) but content that has already been used by another site (Web A)? But it wouldn't be a copy because I remove all that content from web A and create something totally new.

This leaves Web A with an old URL (25 years) and new and original content and, on the other hand, Web B with a new URL (yesterday) but content that was on another website for 25 years.

Moving content from site A to site B is perfectly possible, but I would only do it if there was a very good reason for doing so. The key would be to redirect the old URLs to the new URLs using a permanent redirect. This would mean anyone (or search engine) who visits the old location will be forwarded to the new location.

Any links that are currently pointing to the old content would also send their clicks to the new content.

You mentioned you will be placing new content where the old content used to reside... Will you be using the same URLs for the new content? If so this could certainly pose problems with redirecting clicks to the new location.

This can be done, but be sure you have a very good reason for doing so.

In particular, you can only have one root. You could easily redirect
example.old/exact-page-name
to
example.new/exact-page-name
and then make different names for your now-repurposed example.old, but what do you do with requests for
example.old/
and-that's-all?

Pro tip: When it's necessary to use a site name in a post, use example.com. Or example.anything, if you need to distinguish among different sites: example.uk vs. example.de and so on. Yes, I suppose you could even say example.xxx but We Don't Do That Here.

From my experience, Google always "penalize" moving (redirecting) to new url, if that's the right word.
I always experienced about 30% less traffic, even if that url is just another subdomain, so be aware of that.
Even if Google says it doesn't, they always do.

First you will experience huge drop due to the (de)indexing, and then it will come back after 1-2 weeks, but not the same amount of traffic.

One can redirect any page to any where for any reason. That's built into the system. If one is moving from example.old to example.new, that makes perfect sense.

If one is trying to keep "link juice" by sleight of hand, g will notice and take appropriate action (usually a duplicate content penalty).

If you keep example.old/same-url active, it will have to be a link to the example.new/same-url, which means it can't be different content. This becomes a 301 (permanent) that will eventually be DEINDEXED by g after a period of time (30-120 days) and thus be valueless for the effort of preservation of "link juice".

There also exists the necessity of keeping example.old registered, hosted, and working "forever", which is an additional expense to be considered---until the "permanent" redirect is fully accepted by the search engines.

In my experience, if one is going to change domains make a complete break, give a 90 day window of redirects to have any effect from old to new, then kill (or park) the old domain.
