We are importing all our data from TRN to PRD, everything has worked as expected except when trying to export from the "Deployment" form, all user created tables are imported except the Syteline tables such as item, this has caused problem as we have extended and replaced some of the IDOs and as a result added a column in Syteline's tables such as item.
We have tried exporting using BaseSyteLine as "Access as" however it takes a long time and doesn't result in any files.

Any advise on how to export Syteline's tables ?
Thank you!
