Moving from win7/old pc to win10/new pc

I have a newly built pc on which I will install Win 10. My old pc has Win 7 installed.

I plan to have the new pc boot UEFI. The old pc is legacy boot (non-UEFI).

Q1. Will I be able to just put the old HDDs in the new pc as storage and transfer files (photos, music, downloaded files, documents) from the old HDDs to the new drives on the new pc? Will the UEFI/legacy bios issue have any effect on that?

Q2. How about entire folders like Documents? Can that be transferred or merged between a win7 pc and a new win10 pc? I'm not even sure if it's called the same thing in Win 10 as I don't have it installed.

Q3. How about bookmarks for Firefox and Google Chrome? Are they in the cloud and will still be there when I install and sign into the browsers on the new pc or are they resident on the old pc?

Q4. If I install the old C: drive, which has Win 7 on it, in the new pc as a storage drive will the fact that it has an OS on it cause any conflicts? I suspect it won't because of the boot priority I will set up in the new pc bios.

Besides transferring the HDDs my other option is a 500gb external HD.

You have another option that you might have overlooked:

Or similar docking station.

To answer all your questions, though, yes, you can install the old HDD internally in the new computer and just pull data from it.

For some of the files, whether you use a docking station or install the drive internally, you will have to adjust permissions, but Windows should ask you if you want to do that as an administrator automatically.

That's pretty sweet. I could just throw any sata drive in that station and transfer the data?

Hi,
As stated you will need to take ownership of the 7 hdd first.

Drives format mbr and ntfs is not an issue.

Even if installed uefi C is still ntfs it just has a efi partition and probably a 450mb system reserved or restore partition as well.

Mine certainly aren't "in the cloud". They are purely on my hard drive.

I wouldn't expect yours are in the cloud unless you took some specific measure to put them there.

You can back up any bookmarks now on your hard drive.

"How" varies by browser, but most likely you could do a formal "export" through the browser itself or you could copy a certain folder or folders by ordinary drag and drop.

You might want to just backup your Firefox profile yourself to avoid losing all the saved passwords and such. Just zip up the entire profile:
C:\Users\YourUserName\AppData\Roaming\Mozilla\Firefox\Profiles\custom.default-esr-or-whatever-yours-is-named

I just archive at C:\Users\Elvin Presler\AppData\Roaming\Mozilla and everything in it. Then after reinstalling Firefox, I drop all the goodies into the new profile folder:
(custom.default-esr-or-whatever-yours-is-named).

Those external HDD enclosures are nice too. I have This More Permanent One and This More Accessible One and both work very well. I think I like the layout of that Sabrent one linked a few posts up even better though.
