Hi,
Hope everything is going well.
Do you mean you would like to upgrade your SCCM environment with no internet access? If yes, kindly use the service connection tool when your service connection point is in offline mode. If I have misunderstood anything, please feel free to let me know.
Refer to below articles:
Use the service connection tool for Configuration Manager
SCCM Upgrade with an Offline Service Connection Point | ConfigMgr
Try to follow below process to see if it helps:
1,On your SCCM Server:
ServiceConnectionTool.exe -prepare -usagedatadest .\Data\DataUsageData.cab
2,On your Internet Computer:
serviceconnectiontool.exe -connect -downloadsiteversion -usagedatasrc .\Data -updatepackdest .\Packages
Be sure you are using the downloadsiteversion argument
3,On your SCCM Server:
serviceconnectiontool.exe -import -updatepacksrc .\Packages
After a few minutes, the updates will appear in the SCCM console in "Ready to Download" Status
4,Restart the SCCM service named "SMS_DMP_DOWNLOADER"
Be patient few minutes and the status will change to "Downloading"
You can follow the activities in the logfile named "dmpdownloader.log"
5,When the status is changed to "Ready to install" --> It's ready to install
Hope it helps. Have a nice day!
Best regards,
Simon
