We have ECC6.0 without any Enhancement Packages. We are planning to go either enhancement Package 3 or 4. Right now we are looking at the timing of installing the EPH3 and EPH4n. I came to understand the EPH3 will be using SAINT and EPH4 will be using the installation tool. Also hearing that there are a lot of issue with EPH4 installation.
If anyone has experience implementing both, please advice how much of time of the EPH3 and EPH4 took you, the complexity of installing them and any issues that I need to aware off.
