Hi,
We're seeing some confusing messages here within the support portal regarding the upgrade process.
We were under the impression that the upgrade path is as follows:
Manually upgrade 3.4.9 to 3.5.17;
New upgrade procedure from 3.5.17 to 4.3.7 to finally 5.x
Rumor has it that the upgrade step from 3.5.17 to 4.3.7 will convert the markup language to XHTML ; missing the 4.3.7 upgrade step can possibly cause issues.
Clarification will be much appreciated!
