## Summary
Cross-version upgrade from a **v2.3 or v2.4 baseline** to v2.6.x
currently fails at the 2.5 workspace command
`NormalizeCompositeFieldDefaults`:
```
[QueryFailedError] column ViewFilterEntity.relationTargetFieldMetadataId does not exist
at WorkspaceFlatViewFilterMapCacheService.computeForCache
```
Reproduced locally via Docker cross-version upgrade (v2.6.1 against
`twentycrm/twenty:v2.3` and `:v2.4` images on a freshly-seeded DB).
### Root cause
The column-add is already declared in two places:
-
`2-3/.../1747234300000-add-relation-target-field-metadata-id-to-view-filter`
(backport from #20664)
-
`2-6/.../1798000005000-add-relation-target-field-metadata-id-to-view-filter`
But the runner's `resolveStartCursor`
(`upgrade-sequence-runner.service.ts`) advances forward from
`lastAttemptedCommandName` and never re-runs commands inserted *behind*
the cursor:
- **fresh install through 1.23 → 2.6.x**: cursor < 2.3 → 2.3 backport
runs → column added before 2.5 workspace ✓
- **v2.3 baseline → 2.6.x**: cursor past 2.3 → 2.3 backport skipped →
2.5 workspace `NormalizeCompositeFieldDefaults` crashes ✗
- **v2.4 baseline → 2.6.x**: cursor past 2.4 → 2.3 backport skipped →
same crash ✗
- **v2.5 baseline → 2.6.x**: cursor past 2.5 → 2.5 workspace already
applied (ran against v2.5 source's older entity without the column) →
2.6 fast adds the column ✓
The 2.6 fast `1798000005000` runs *after* the 2.5 workspace command, too
late to help v2.3 / v2.4 baselines.
### Fix
Mirror the existing 2.3 Early backport at two more versions:
-
`2-4/.../1747234400000-add-relation-target-field-metadata-id-to-view-filter`
— covers v2.3 baseline (runs in 2.4 fast, before any 2.4/2.5 workspace
command)
-
`2-5/.../1747234500000-add-relation-target-field-metadata-id-to-view-filter`
— covers v2.4 baseline (runs in 2.5 fast, before
`NormalizeCompositeFieldDefaults`)
Both use `ADD COLUMN IF NOT EXISTS` (idempotent) and `DROP COLUMN IF
EXISTS` for the down. No FK / index — those still live in the 2.6 file,
which runs as a no-op for the column on already-fixed DBs.
Pre-2.6 codebases can't use `@WasIntroducedInUpgrade` (#20686 only lands
in 2.6), so this "ladder of backports" remains the operative pattern.
## Audit context
Locally walked `v1.23 / v2.0 / v2.1 / v2.2 / v2.3 / v2.4 / v2.5 →
v2.6.1`:
| Baseline | Result |
|---|---|
| v1.23 | PASS |
| v2.0 | PASS |
| v2.1 | PASS |
| v2.2 | PASS |
| **v2.3** | **FAIL** (this PR) |
| **v2.4** | **FAIL** (this PR) |
| v2.5 | PASS |
