I did the following and succeded in all but bug-tracker (to my knowledge).
Run the upgrade.sh.
Copy zzz-upgrade.tcl to /tcl
Start the server.
Remove zzz-upgrade.tcl
Restart the server.
got to /acs-admin/apm/packages/install.
Select *all* upgrades and workflow. *SKIP* bug-tracker.
When you come to select the SQL files, skip the following:
notifications 4.6.1-4.6.2
content-repository 4.6.1-4.6.2
subsite 4.5-xxx
etp 1.1d-1.2
fs everything <4.6.2
forums *all*
install (should run smoothly)
restart the server
install the bug-tracker upgrade
unselect all data-model scripts and upgrade.
run bug-tracker.sql (special file)
restart the server
realize bug-tracker does not work 😟.
