Hello All, I have upgraded multiple server from Appian 7.7 to Appian

If you are referring to the: "InvalidTypeException" that error can be safely disregarded, it simply indicates the DESIGN engine hasn't finished propagating the data types to the rest of the engines, ones it finishes those errors disappear. This shouldn't prevent the environment from working properly.

Thanks Eduardo,
Actually I want to know the reason for below errors and how to resolve this:

ERROR com.appiancorp.plugins.LoggingPluginEventListener - Failed to enable Plug-in 'Puppeteer' (com.appiancorp.psshared.puppeteer) version 1.1.2: 'There was a problem loading the descriptor for module 'TaskPuppeteer' in plugin 'Puppeteer'.

The plug-in errors? You may want to get the latest versions for those. There's a TaskPuppeteer for JDK7 on Forum under Shared Components, the other one I don't think it has been recently updated.
