CRM 2007 and Custom ISA 4.0 application interoperability


We are in the process to upgrade our CRM 4.0 back end system to CRM 2007, in fact we already performed the BASIS upgrade in our sandbox system to estimate the effort required for the upgrade on different areas.

One of this areas is related with the ISA web application, we have a custom ISA 4.0 application that we use to capture business transaction in our CRM system, but this application is running in a separate NetWeaver 7.0 system on the DMZ, we would like to know if it is possible to integration of the old ISA 4.0 with the new CRM 6.0 (CRM 2007) backend system.

The reasoning to try to leave the CRM ISA application on 4.0 is because we are using it just to provide us the framework to create transaction in CRM, in fact we only create one type of transaction in the CRM system from this web application and the effort to upgrade the java application to the new version together with the support package stack could be very high for a application that is not very heavily used.

In summary, the question is if it is architecturally feasible to connect a CRM ISA 4.0 web application with a CRM 6.0 (CRM 2007) backend system?

Thanks for your help with this,
