Business growth brings new challenges to business. Changing business scenarios result in releasing new product versions with better features and new functionality. The challenge lies in upgrading from a lower version of a product to its higher version without losing track of critical information and being user friendly at the same time.

All of us would have upgraded to a better version of a product. Firefox and IE had introduced new browsers quite a while ago. We have all upgraded to the newer version which has better features and new functionalities. The data migration would essentially be the bookmarks or favourites, RSS feed etc.

Just imagine an ERP system with millions of records holding business critical information. How do users migrate to a higher product version without losing or modifying the existing data? How can the migration be done without much complication?

The solution lies in designing an easy to use migration tool. A detailed analysis of both the lower version and higher version of the product needs to be done in terms of comparing the features and functionalities. This comparison needs to be done at the database level and at the user interface level. Based on the results of the analysis the tool needs to be designed and developed. The underlying factors that need to be considered are: the need for minimum user intervention and the ability to restart from any point without the need for an entire rollback of data. This is not just for an ERP but for any product upgradation. I have just given a global view of the solution but as you dwell upon this you would come across various challenges or maybe a better solution. 🙂
