One of the questions that arises often about a upgrade version of software is how it checks for a previous version. This question has been more popular with the new CorelDRAW X6 Upgrade Policy. Remember that users of all previous versions are eligible for upgrade pricing until June 18, 2012. After that (and with future versions), only users of the most recent two versions are eligible for the upgrade price.
If you install the upgrade version of CorelDRAW X6, it will ask for a serial number from CorelDRAW X4 or X5. It will not look to see if a previous version is installed. This allows you to install it on a new computer without having to install an older version first. Just make sure you have those serial numbers stored in a safe place so you can find them when needed.
So what about the users who take advantage of the grace period to upgrade from older versions? Those users will be provided with a CorelDRAW X4 serial number to use when installing the upgrade. Again, make sure to save both the CorelDRAW X4 and CorelDRAW X6 serial numbers so you’ll have them should you need to install again later.
The new upgrade policy makes it very important for users of older versions to upgrade before June 18, 2012. Either pay $199 now for the upgrade or pay $499 later to buy the full version.
