How to migrate from bootcamp windows 10 to mac

The advantage of removing the Boot Camp partition when you have everything sorted is that you gain all the empty space on it. Depending on the chosen size, this could be quite a lot. From experience, make sure you have at least one secure backup of the Mac side (Time Machine and/or clone) before you delete the Boot Camp partition. For some reason, I found that I had to erase the internal drive and restore to make the empty partition finally go away.

Of course, if you want to try the Parallels option, it is probably best to do this before you remove the Boot Camp, so you can import everything. I did this on a 2017 iMac 18,3, though I ended up doing a fresh install of Windows 11 on account of some imported bugs. These days the update from 10 to 11 is no longer free and automatic. The original Fusion hard drive was replaced with a new SSD, and it works well enough for me, though slower than on my M1 Macbook (where launching Windows takes around 15 seconds).

Without being an expert on the subject, I guess the Windows keyboard and mouse will work on a Mac. Give it a try before you do anything else.

I only have experience of IMAP accounts in Outlook, where the settings are exactly the same for Mac and Windows. It is worth setting up Outlook on the Mac, and checking that it works, before deleting it from Windows. Microsoft seem more forgiving about that sort of thing than they used to be, and their support service can sometimes be helpful.

Hoping you find a good solution.

The difficulty is that Windows cannot read or write to the Mac partition. The usual recommendation is to copy the files to an external Windows flash drive (ExFAT is often recommended, though the one I used is MS-DOS Fat32) that can be read by Mac. If you have OneDrive or Dropbox, these have also been used. If there are vital files, it is a good idea to have at least two backup locations (drives). With my Intel iMac, I wanted to move to Windows 11, and a virtual environment (e.g. Parallels) is the only way of doing this. It gives the option of migrating the Boot Camp drive into a virtual drive as part of the Windows 11 installation, so that the original partition can be removed. As an alternative to plan A, if you have the time, you may experiment with a trial copy of Parallels Desktop that lasts a week, and see if it works for you.
