6.9 Resume Workflow Execution

Start all EC/ECSAs that were shut down during the upgrade.
```
$ mzsh startup <ec names> <ecsa names>
```
Restart the disconnected ECSAs and start the real-time workflows.

In order to minimize downtime, restart the disconnected ECSAs one by one.

To stop running real-time workflows and restart an ECSAs:
```
$ mzsh shutdown <ecsa name>
$ mzsh startup -f <ecsa name>
```
The file $MZ_HOME/lib/picostart.jar will be updated on the ECSAs.
Start the workflows on the restarted EC/ECSAs.
Enable all workflow groups, from the Execution Manager in Desktop, or by entering the mzsh wfgroupenable command, for example:
```
$ mzsh mzadmin/<password> wfgroupenable \*
```
