That's a pretty big migration.

This is what it says for the 21.4 upgrade

This guide assumes you are on Appian version 20.2 or higher. If you are on a lower version of Appian, upgrade to 20.2 first before upgrading to the current release.

When you check out 20.2 it says the following: 

The following steps are required to upgrade self-managed installations of Appian to the current release. If you are on a version of Appian lower than 19.1, you must first upgrade to 19.1 or higher before upgrading to the current release.

I'm not sure if you can go straight from 17.1 to 19.1 - and the documentation for 19.1 doesn't seem to be available. I would suggest you contact support to get that information.

Is this about the migration of the Appian platform or about the applications?

For the applications, I suggest to set up a test environment and do a functional test. In general, Appian is backwards compatible. Check plugins and versions. Then plan some time to update the applications to the new or changed functionality.

Hi Stefan,

 

Application as well as Infra needs to be migrated.

Is it correct to assume that import of package to the higher version will work considering we remove all the deprecated function/smart services and plugins..?
