Install the Aloha CD on the new PC, with services.
Using the number of terminals correctly, etc.
Copy from the old HDD only these folders:
All Dated Subs (for your history)
BMP
NEWDATA
PROFILES
into the new Aloha Directory on the New PC.
Run the database upgrade utility (\aloha\bin\dbconfig.exe)
Refresh data.
Now you also need to make sure that your environment variables are the same as they were on the old PC.
Especially:
NUMTERMS
SERVER
IBERROOT
IBERDIR
TERMSTR
They should also match the variables that each terminal is using in their IBERCFG.BAT files.
The server should also use the same Computer Name as the old Computer. This can involve some tricks if you are copying the files from the old PC over a network. (not recommended for a noob.)
Also, blok's suggestions:
Make sure it is the same hard drive letter, path, etc. You will need to register services and certain files. Also need to share drive as BOOTDRV with full permissions.
But you don't need to register dll's again, because the CD load will do that.
