I am preparing to upgrade to the 7.5 version from the current 5.0 version. Based on the documentation I've read it seems to be a new install and not really an upgrade.
Basically I am planning to do a backup of the current system - files and folders, unistall 5.0 and then install 7.5 using the methodology provided by SAP. Once that is done .. restore the files and folders from the backup..
Could you let me know whether this is the optimum approach. Also are there any things I should look out for while performing this.
