This article was created in response to a support issue logged with K2. The content may include typographical errors and may be revised at any time without notice. This article is not considered official documentation for K2 software and is provided "as is" with no warranties.


The following error appears during Package and Deployment:

"Unsupported schema version 24 - version 23 or earlier is supported. Please update to the latest version. Parameter name: xml"



Deployment will fail and you will not be able to deploy your solution to the destination environment.


You need to install the same version of K2 Five Fix Pack on the destination environment as on the source environment. The environments are not in sync and is causing this error.
