I've taken the plunge and upgraded to the 6.1 enterprise only to find that is has mutilated my page formating. Some of which is tied to the BEGIN and END fieldblock tags, I know I've had issues with these previously and asked what was the proper way to use these when modifying the site beyone a standard verticle output. Any suggestion to have the transition take place without having to rework things?
It all depends on what version you converting from and what sort of changes were applied to the templates. In general conversion from version 6.0 should be seamless. Contact support directly sending your project files if you are looking for a more specific advise.
