Impossible to say. From "just works" to "break environment". If you have to, be prepared to do a full restore of your environment.

Thanks for suggestions everyone, we upgraded to 20.4 and went with deployment, but for my knowledge,

what kind of issues might occur, if we change the version in Manifest file and deploy

Vineeth, DO NOT manually edit any files in your appliation zip. Only deploy your application once your production environment is upgrading to 20.4. It's better to have a small delay in your release to production by waiting for the 20.4 upgrade on PROD than to have potentially worse problems by going with an unsupported solution.

I would strongly recommend you do this deployment once your production environment is upgraded to 20.4. Even if you haven't used any of the newer 20.4 features, i've experienced in the past that forcibly importing objects from a newer version to an older version can sometimes cause very large side effects due to the import file itself containing functionality that the older version doesn't know how to handle. Especially when you're talking about an entire application package.

If you anticipate large delays between environment upgrades in the future, you should stage your version upgrades appropriately to take this into account.

Just wanted to understand, as we know , there are no features of 20.4 has been used, as our Dev Environment is 20.3, if we deploy the Application , will it effect the other application or the whole Appian tool ?

If your dev environment is on 20.3, then can you deploy from that environment instead?

we have not used any new feature, as our dev is 20.3 and prod is 20.3,

only QA is 20.4

This is what I meant with "not supported". It might work if you do not use any features of the new version, but if things go wrong, you are on your own.

but when i changed the version in the Manifest file and try to import and inspect, it dint threw an error,

There is no supported way of doing this.
