We are planning to migrate zimbra OSS to NE.
I am looking the comparison of zimbra products. As per my understanding(let me know if i am wrong) in NE there are two sub edition one is standard(not open source) and second is professional edition.
The main difference between these two's are outlook connector.
Now my question is, is that possible to run standard and professional edition at the same time on the same server. If i purchase standard license of 100 users and latter i want to upgrade only 10 users to professional edition.
