Encounter DEF file export

rayz

I am trying to export my layout from Encounter to Cadence DFII ennvironment using DEF format.  Apparently the DEF file generated by Encounter does not contain all the VIA definitions or Virtuoso has problem reading them since when the design is imported in Virtuoso some of the VIAs are missing and I see warniong message that VIA definitions are missing. Do you have any experince dealing with this issue.

Thanks
