Hi
Thank you for reaching out to the Live Community. Please allow me to address your questions.
I hope you are aware that from March 2023, the Windows Azure code signing patch is must to upgrade the agents.

Once you have ensured that the Patch is supported, kindly check whether your OS version supports 7.9 CE version upgradation. You can find same in above link.
Once the prerequisites are checked, you can follow below instructions to upgrade the agent:
1. Create a installation Package with the required version(Endpoints->Agent Installation):
2. Go to All Endpoints-->Find out the Server on which agent upgradation is required--> Right click and select Upgrade Agent version.
2. Select the installation package which you have created and upgrade.
3. Another way is to do it from Action Center.
a. Go to Incident Response-->Response-->Action Center & select New Action.
b.Select Agent Upgrade --> Select Windows --> Choose Installation Package --> Click Next
C. Select Targets and schedule the update.
Please mark the response as "Accept as Solution" if it answers your query.
