If we are speaking about Quantum PLC, then you have 2 options to move. You can use Unity Pro software or the traditional Concept software. If you go for brand new installation now, go for Unity Pro if you are sure. If you want to maintain some old PLCs, existing istallations, then go for Concept. Both Softwares have almost the same functionalities. If you have modicon Momentum PLC, then you can only use Concept. The actual version is 2.6 SR2.

We are modifying an existing installation of Modicon Quantum (hot backup) system. The previous vendor who installed the PLC has used Concept 2.1. We have modsoft as well as Concept 2.6. The PLC backup given by the vendor does not open in the newer version of Concept, it gives a message that the 2.1 version is required. Has anyone faced a similar problem before? It seems that the version 2.1 is no longer sold.
