I took over a website where version 5.2 is installed.
There are many contacts and mailings there.
I have installed version 7.x and can now see both entries under the Extension menu. Unfortunately, version 5.2 has not been updated.
I have following questions:
- How can I convert 5.2 to 7.x?
- How can I migrate from 5.2 to 7.x? Contacts, mailings, etc.
Does somebody has any idea?
