Only in some special cases the upgrade process of Seven requires manual tweaking.
Upgraded start scripts are installed in the
bin directory under the name
'seven-new' and
'seven-new.bat'. Because it is
common that deployers have modified the start scripts, and the
possibility of the OS having a lock on the start script, the
upgrader can't overwrite these scripts automatically. The
updates to the start scripts can be merged into the current
start scripts, or the current ones can be replaced by the new
start scripts.
