Reduce the amount of time needed perform a CM upgrade
For most companies, Configuration Manager is becoming a mission critical service the requires less and less downtime. Upgrading large environments/DBs can take up to 5 hours for the CAS, and 4-5 hours for primary sites. Also, most customers want to get the latest hotfixes installed right after performing an upgrade. In some cases, the hotfixes take just a long to complete as the original upgrade. Overall, this can require long outages (sometimes 2 days) to get current.
The ability to upgrade directly to the latest hotfix as noted here:
Reduce the time needed to regenerate DRS sprocs and reporting views. These two steps seem to take about 80% of the overall upgrade time.
We have made optimizations during SCCM upgrade to not do unnecessary SQL tasks. We are not considering upgrade directly to the latest hotfix.
