Exporting files from Passolo 2016 to other formats

We have the Passolo 2016 edition and following business requirements we need to export some files to formats recognizable by other CAT tools (e.g .xml , .xliff etc.) for further editing, finally import them back to 2016.


As per our tests we need the Passolo 2016 PRO version in order to the able to successfully export the files in other formats.


Considering that 1) 2016 PRO version is not available; anymore, and 2) 2016 files are not compatible; with the newer Passolo 2018 edition to support this, what are our options?
