I am running Jenkins (2.121.2) as a container backed by EFS as file store with amazon-ecs:1.11.
I recently upgraded the plugin to amazon-ecs:1.16 by modifying plugins.txt (which is run in jenkins Dockerfile)
After upgrade I can see that the plugin version is latest but the configuration page for ecs still shows old screen (no fargate, Template Name/Task Definition Override etc configurations)
I then uninstalled amazon-ecs:1.16 plugin, restarted my jenkins and then installed amazon-ecs:1.16 through console again.
Even after that, I am unable to see the new configuration. Is there something wrong with my upgrade process. If so, please guide
