Article Robert Cemper · Mar 5, 2021 3m read Using ECP across IRIS and Caché Migration from Caché to IRIS can be quite a challenge if your code is grown over many years and probably not so clean structured as you may like it. So you face the need to check your migrated code against some reference data. A few samples might not be a problem, but some hundred GB of data for testing might be. A possible step could be to have your fresh code in IRIS but leave your huge datastore on Caché and connect both environments over ECP. I have created a demo project that gives you the opportunity to try this based on 2 Docker images with IRIS and with Caché connected over ECP. #ECP #Caché #InterSystems IRIS 12 2 0 474
