I upgraded W8.1 to W10. Now update to Win10 Pro (by entering key)?

HI

few days ago i clean installed W8.1 on my laptop from msi (GT72-2QD, W8.1 was preinstalled) and then
i immediately upgraded this installation to W10 home for free. The upgrade installation was
correctly activated and is running fine. Today i'd like to update to Win10 Pro by entering/changing
the serial key. I've done this before on my second laptop from msi (msi GE60-2PE) but before
upgrading to W10Pro i clean installed W10 home on this machine.


My question:

is it possible to perform a second upgrade on the same machine without any problems with e.g. activation,
settings i made in W10 home..., etc, ?



Upgrade by entering key (see post #02): Upgrade W10 Home to PRO ?

If you wanted to upgrade, you would only have to change the product key to enter the Pro key to quickly upgrade with a restart. No need for a full blown upgrade install.

thx!
