I think I found an inconsistency in the wiki upgrade instructions.
is missing instructions to copy the following directories to the new installation directory:
* Move all directories for each site * openemr/sites/default/documents * openemr/sites/default/edi * openemr/sites/default/era * openemr/sites/default/letter_templates
It only instructs the user to move the default/documents directory, but it should also advise the user to move the other directories. Furthermore, I wonder if it ought to be, “copy” rather than “move”?
I will be happy to update the wiki if you want.
