** [tickets:#1401] smf: upgrade time improvement**
**Status:** fixed
**Milestone:** 4.7.FC
**Created:** Mon Jul 06, 2015 08:58 AM UTC by Rafael
**Last Updated:** Wed Sep 30, 2015 09:34 AM UTC
**Owner:** Rafael
Decrease the execution time for campaigns by merging parallel procedures.
Parallel procedures are procedures that have saSmfExecLevel set to the same
value. When procedures are merged they will be executed in one thread. Today
procedures are executed in separate threads with possible cluster/node reboots
in each procedure. When procedures are merged they would install multiple
software packages on a node with one reboot at the end.
There are three use cases
* Upgrade one node at the time in the cluster
* Upgrade all nodes at once using cluster reboot
* Upgrade several nodes at once
There will be an IMM attribute that decides if procedures are to be merged to
maintain backward compatibility.
