You cannot do an upgrade from a 32bit version of Windows (any flavor) to a 64 bit version. Going to a 64 bit version requires a clean install and then reinstall of all applications. If you are into a CLEAN install ignore the following 32bit rant
You CAN upgrade to a 32 bit version of Windows 10. The 32 bit versions monthly update files are about 50% smaller, updates install more quickly and you have a lesser chance of getting into update failure hell.
disclosure: although I was running Aloha at 3 stores I am currently running another POS at those stores. I only run aloha at one location and it is on all new equipment & 64bit Windows. I do run over 25 computers in my organization and my 32 bit Win machines are 10 point of sale terminals (win7 and Win10 LTSB) and 2 BOH machines. They all ran Aloha 6.7 3 years ago but run the latest version of onePOS now.
If you are somewhat PCI/DSS compliant (win 7 sundowns in January, xp embedded
?) and not using your Aloha BOH for anything but Aloha purposes a 32 bit version will work FINE for you (unless NCR/Radiant is forcing people to 64 bit) I am kind of out of the Aloha loop now except for the 1 store and my reseller handles almost everything there (10pro on BOH YUUCK. Unless you have more than 4GB ram on that computer 64 bit is not necessary to access most of your ram. 32 bit systems I run with 4GB of Ram usually have between 3.4 and 3.6 GB available, most terminals still only have 2GB anyway.
I am sure it is true that 32bit operating systems WILL go away sometime in the future, but they are still around for now and I would put off going to 64 bit in your situation, When you get a new computer, then you could go 64 bit and bite the bullet on clean install.
There will be some piece of new hardware, printer, scanner etc that comes along some day that will not have 32 bit drivers. As long as you are not out buying every new device you see you should be good for a while.
By the way Win 10 Pro is a terrible operating system for a restaurant. Forced "feature" updates every 6 months, flashy Windows store apps popping into place (GAMES ON MY BOH COMPUTER.... Microsoft, "get a clue!") A long way from a stable software install that you can forget about for 10 years. 4 New POS terminals I bought 3 years ago all came with Enterprise LTSB... much better.
If there is any way you can get an Enterprise version or better yet LTSC (Enterprise Long Term Servicing Core) you will be much happier. (Unless you plan on running apps from the Windows Store which I have NEVER found necessary in ANY of my stores) There are even work arounds to run windows store on LTSC but they are for computer Mavericks.
