Appian 18.3 to 18.2 downgrade

Question

Hi, 
 Due to client reasons we need to move some code developed in Appian 18.3 (cloud) to another Appian instalation in 18.2 (on premise) . So, we need to downgrade. 
 We need to know if it works in the same way that the export/import application utility. Is there any problem? 
 Thanks a lot

Hi Aitor, 
 
As Joe mentioned, deploying applications from a later version to an earlier version is not supported. 
Also, modifying application export files to import them into another environment is not supported and can cause issues down the line with these objects and your environment.

hi aitor.sanchez , 
 
You cant take patch and deploy to lower version. 
I would suggest you to copy paste the code in txt and update in lower version. 
 
Thanks,

Hi aitor.sanchez, 
Lower versions of the Appian code can be deployed to higher versions of Appian but the other way is not possible via Import or Export. I think you need to manually do the changes.
