Where can I download the appropriate version of Agile Accelerator for ALM v11.52?

I know that v10 is out of support, but does anyone have any suggestions?

Need to update several requirements Release at the same time. I can select multiple records but when I click the details button, I can only update one requirement. How to update multiple requirements at the same time?

Error when importing v11 QCP file into ALM v12.... "Invalid Entry Size" error.

I heard that I cannot upgrade QC v10 to ALM v12.2 directly. Is that true.

We often working with HP support to troubleshoot issues. We use ALM logging and sometimes forget to clean up the logs which leads to disk space issues. Is there a way to automatically clean up the logs in case we forget?

We are importing projects from an acquired. These project will be upgraded from v11.52 to v12.2. We have a request for the next defect Id to start at 10000 going forward. The last defect before the upgrade is 7541. Any ideas would be appreciated.

Please explain what this means.

I have a project that I want to create a new domain for. How can I change the project to the new domain?
