Does WebSphere have a similar feature like side by side deployment/versioning as in Weblogic. I need to deploy my application on WebSphere with minimal downtime/restarting the Clusters. Any pointers on this will be helpful

All depends on your version and specific requirements. See some options below.

You must have WAS 8.5.5 or later. Then you could use Application edition management see Deploying and managing application editions with Intelligent Management

For earlier versions you could use rollout update. Rollout Update sequentially updates the configuration on the nodes that contain cluster members.

Or manual process described here - Maintain continuous availability while updating WebSphere Application Server enterprise applications
