Issue

.tde files cannot be upgraded to hyper on Tableau Server and hence cannot be encrypted on Tableau Server.

Environment

  • Tableau Server
  • Tableau Online
  • Mixture of .tde and .hyper published data sources

Resolution

Follow these steps:
  1. Download the .tde into Tableau Desktop.
  2. Click the extract and choose Create a NEW extract which will create a .hyper file.
  3. Republish the .hyper file which can now be encrypted.
For more information, see Extract Upgrade to .hyper Format.

Cause

Encryption at Rest cannot encrypt .tde files (only .hyper).
