# Using a different version of SUM with an SPP ISO

##

To use a different version of SUM than the version that was packaged in an SPP, use the Custom Baseline function in SUM. Replacing the SUM files in an SPP ISO manually might create issues with deployments.

NOTE:

SUM can create a custom baseline or ISO with components from SPP 2016.10.0 and older, but it cannot include SUM versions earlier than SUM 8.0.0.

Procedure

1. Download a copy of the SUM ISO you want to use and save it in an empty directory, and then mount the ISO.
2. Download a copy of the SPP ISO and save it in an empty directory, and then mount the ISO.
3. Open the version of SUM you want to use with the SPP components.
4. Add the mounted SPP (`..\spp\packages`) to the SUM session.
5. Create a custom baseline using the SPP components, and then select the version of SUM you want to use as the version to include in the custom ISO.
