While the upgrade process is in progress, you can continue working in the deployment tool. You can request deployments of specific artifact versions any time, even before the version has been upgraded. When you issue a deployment request for a specific version, the server checks whether the version is upgraded. If version has not been upgraded, the upgrade process starts immediately.
For example, if you request a deployment with version 1, and that version has not yet been upgraded, the server upgrades the version, and then the server continues with the deployment.
The upgrade process reports upgrade progress. Click , and view the progress bar and percentage. When the upgrade process finishes, the progress bar closes.
