--- Comment #13 from Mike Kaganski <mikekagan...@hotmail.com> --- Firebird itself does not support older on-disk structures (ODS). This is true both for version 3 [1], and version 4 [2]. (Release notes for v4 do mention a hack to support ODSv12 by copying a library from older version to /plugins; while it could in theory be made for Windows, it's likely totally impossible for Linux, where we rely on system FB, and thus custom (self-built?) library for FB3.0 could fail to work with system FB4.0.) The 12 vs 12.2 change was described in FB 3.0.4 release notes [3]. It is described to have impact on macOS and 32-bit Linux; and note this excerpt: > Existing databases ... are always opened successfully with Firebird 3.0.4 > on the platform *where they were initially created* The overall policy of the project seems to require use of backup-move-restore procedure whenever you want to move a BD to a different system; LibreOffice embedded engine itself save the backup of the FDB, not the FDB itself, for that reason. By the way, IIRC the ODS even of the same version will differ on Big-Endian vs Little-Endian machines, making direct move of a FDB of the same ODS version impossible. And hence I consider this issue to be NOTABUG (assuming that it was a user error not using the proper procedure when moving the database), or NOTOURBUG (taking into account the phrase "A legacy provider for databases with ODS 8 to 11.2 is planned for a future sub-release" from 3.0 release notes, which is curiously absent from 4.0 release notes).
