Hi @Muralik90410122 

you cannot downgrade your PDI, you can only go with higher version, see this:

Downgrading is possible only for non-PDIs, as the whole instance data are kept for 7 days by ServiceNow, so when you create a case they can move the data back to the 7 days (when the upgrading was within this time window).

However this is not available for PDI. Only you can do is to backup your work (update set, xmls, csv, whatever you need) then release the instance and request a new one.

Hi @Muralik90410122 ,

Not possible. You can chose between Xanadu or Yokohama release.

Hi @Muralik90410122 

Downgrading a ServiceNow instance is not supported. 

Alternatively, you can capture your configurations and customizations in an Update Set and then request a fresh instance.
For more clarity and best practices, you may refer to related posts and community discussions here:

@Muralik90410122 Downgrading the instance to a lower version is not possible. 

What you can do is release the current PDI instance and create a new PDI instance with the Vancouver version if available.
