Migrating Billing Software - Modernbill 4.x to WHMCS

We have 3 separate Modernbill 4.x systems that we wish to merge into 1 single WHMCS system.

Using the provided migration scripts, the issue we face is that there could be duplicated invoices numbers etc. This cause a clash and can result in clients ending up with invoices from our different systems.

We need a plan to ensure that invoice numbers, client IDs etc do not clash.

Please state your plan of attack in your quote.

Thank you.

UPDATE 1: We will need non-expired credit cards to be migrated as well. We do not want expired cards in the system to be migrated.

Skills: MySQL, PHP, WHMCS
