Operators usually have a rich track record of commercial offers, products, serving different customer segments and accumulated over the years of operations. This constitutes a complex picture at the time of transferring this onto a new BSS and needs careful consideration in the early days of the project.

Aside the offer and product pruning exercise ahead of the new BSS program, a phased swap strategy can be an efficient way to mitigate the risks and increase the chances of a successful swap. The phases can be defined either by :
A first sample of friendly customers can also be migrated to allow the validation on a simpler combination of offers and products. All those possible scenarios need to be looked at and assessed to design the safest and more robust program.
