OTRS4 migration - duplicate key value error

  • Used Zammad version: latest (just installed this morning, haven’t logged in to see a version)
  • Used Zammad installation source: (source, package, …) Ubuntu repo
  • Operating system: Ubiuntu 16.04.4
  • Browser + version: Firefox

Expected behavior:

  • Clean import

Actual behavior:

  • failed import

Steps to reproduce the behavior:

Install plugins into OTRS and select import from Zammad
PG::UniqueViolation: ERROR: duplicate key value violates unique constraint “groups_pkey” DETAIL: Key (id)=(2) already exists. : INSERT INTO “groups” (“id”, “name”, “note”, “updatedbyid”, “createdbyid”, “createdat”, “updatedat”) VALUES ($1, $2, $3, $4, $5, $6, $7) RETURNING “id”

I gave the VM a bit more RAM (2GB) and cut down the amount of RAM elasticsearch (JVM heap 512m) used, and the import seems to be working.
