SDM unapply support stack and deploy lower sps

[dan_pfingsten2]

Our portal sits on nw2004s java stack only (700 and support stack 11). Would like to rollback sps 11 and apply sps 10 so that it matches our BW ABAP support stack level. Is this possible to rollback the java stack support stack level?

The thought is to use SDM to undeploy all components, select all sps 10 components (SCA's) and deploy.

Would appreciate any comments in regards to this, is this the corrrect procedure or even possible?

Hi,

The SDM is one of the options to choose for undeploying an application. But I basically prefer using the J2EE Engine's visual administrator tool (it is more intuitive in my opinion). Here's how to deal with it:

1. Start the tool using the go.bat located in \usr\sap\<SID>\<Instance Name>\j2ee\admin folder

2. Log in with an Administrator user.

3. Under the Server node click Services-> Deploy.

4. In the runtime tab, on the right hand side screen click on the Applications checkbox. The list of all deployed applications appears.

5. Select the application and click on the Remove button.

Undeploying using SDM

You can also undeploy the application using the SDM tool. Launch the tool by running the remotegui.bat from your usr\sap\SID\JC00\SDM\program. Enter your sdm password and then go to the undeployment tab. pick the application you want to undeploy and add it to the right hand pane and follow the steps in the wizard

Check this official SAP link for deployment and undeployment details.

The end result was that we restored back to sps 9 and then applied sps 10 again and no problems. The undeploy process at best seems unpredicatable and risky. We tried and ran into many issues. So the advice is to keep current incremental backups of your central instance and database.

Hi,

1.Undeploying all the components through SDM is a risky process,because components already deployed will have somany subcomponents which have to be found and undeployed.

2.So, better option is to deploy components of SP10 through SDM,by selecting an option "<b>Deploy any version</b>" at the bottom corner.

3.Make sure that all the components are brought back to SP10 and suitable kernel is applied.

4.Better practise is to take a backup of existing version before going to upper version.any time you can revert back to older version by restoring the backup.

In a sandbox environment, I tried the undeploy of components, selected all sps 10 and deploy using the SDM gui.

The GUI shows: Step 2 of 4: Show Deployment Proposals for SCAs/SDAs to Be Deployed' and appears to be hung as it just clocks. The log is not showing any error messages or furthur activity.
