Or you can use the commands below to download a specific version yourself and transfer it to the relevant server (Manager, Worker and Cache are images that may be required depending on your common, Integration and Portal license).

sudo docker pull apinizercloud/manager:2022.xx.1
sudo docker save apinizercloud/manager:2022.xx.1 > manager_2022.xx.1.tar

sudo docker load < manager_2022.xx.1.tar
