Hello
You will need to do a Homogeneous System Copy as there is no change in the OS and DB.
As this is a Java stack there will be application data at the file system OS level.
If you do a backup and restore only the database is restored.
In order to get the application data present at /usr/sap/SID/JC00 you will need to copy them too.
As this is a Windows machine I am not sure whether copying the files manually to the new /usr/sap/SID/JC00 location will work.
I suggest you to do Java export and Import using sapinst. If you go for export and import then there is no need for backup and restore.
Cheers
