|The only way is to temporary install the hard drive from the old computer into the new one. If you cannot install the drive in the new computer a USB enclosure should do it.|
You will be able to copy data files, videos, wp documents, sound files etc. The operating system is largely irrelevant.
What you wont be able to copy and expect them to work is the programme files unless they are very simple programmes. They will need to be reinstalled on the new computer.
