How to Fallback to an older Software Release
From TBwiki
If you have access to the web portal, you only need to select the old package and activate:
Systems -> Sytem_1 (edit) -> Activate package
Otherwise, SSH to the management port
vi /lib/tb/toolpack/setup/12358/2.5/apps/tboamapp/tboamapp_wd_cfg.ini
Modify this line to use a valid release:
TB_PKG_PATH = /lib/tb/toolpack/pkg/2.5.72
Then stop and restart Toolpack:
tbtoolpack stop tbtoolpack start
You can also use tbx_cli_tools_remote application and check the tboamapp log to see if you can spot an error.
