-## Troubleshooting
-
-### `PermissionError: /var/lib/odoo/sessions`
-
-Odoo 17 berjalan sebagai user dengan UID/GID `101`. Perbaiki ownership
-named volume Odoo tanpa menghapus database atau filestore:
-
-```bash
-cid=$(docker compose ps -q odoo)
-docker exec --user root "$cid" sh -c \
-  'chown -R 101:101 /var/lib/odoo && \
-   chmod 755 /var/lib/odoo && chmod 700 /var/lib/odoo/sessions'
-```
-
-Verifikasi bahwa user Odoo dapat menulis session:
-
-```bash
-docker exec --user odoo "$cid" sh -c \
-  'touch /var/lib/odoo/sessions/.write-check && \
-   rm /var/lib/odoo/sessions/.write-check'
-```
-
-Gunakan satu volume utama berikut pada `docker-compose.yml`; jangan membuat
-mount terpisah untuk `/var/lib/odoo/session` (singular):
-
-```yaml
-volumes:
-  - saat_odoo_filestore:/var/lib/odoo
-```
-
-### `column res_lang.short_time_format does not exist`
-
-Pastikan versi image Odoo sama dengan versi database. Database proyek ini
-adalah Odoo 17, jadi gunakan:
-
-```yaml
-image: odoo:17.0
-```
-
-Jangan menjalankan database Odoo 17 dengan image Odoo 18 tanpa proses upgrade
-major-version yang resmi.
-
-### Tidak bisa login sebagai `admin`
-
-Jika log menunjukkan `Login failed` dan user `admin` aktif, reset password
-melalui ORM Odoo menggunakan nilai `ODOO_ADMIN_PASSWORD` dari `.env`:
-
-```bash
-set -a && source .env && set +a
-docker compose exec -T -e RESET_PASSWORD="$ODOO_ADMIN_PASSWORD" odoo \
-  odoo shell -d "$POSTGRES_DB" --db_host=db --db_port=5432 \
-  --db_user="$POSTGRES_USER" --db_password="$POSTGRES_PASSWORD" --no-http <<'PY'
-import os
-user = env['res.users'].search([('login', '=', 'admin')], limit=1)
-if not user.exists() or not user.active:
-    raise RuntimeError('Active admin user was not found')
-user.write({'password': os.environ['RESET_PASSWORD']})
-env.cr.commit()
-print('Admin password reset')
-PY
-```
-
-Setelah itu login dengan user `admin` dan password `ODOO_ADMIN_PASSWORD`.

+## Troubleshooting PermissionError sessions
+
+Jika muncul:
+
+```text
+PermissionError: [Errno 13] Permission denied: '/var/lib/odoo/sessions'
+```
+
+Odoo 17 berjalan sebagai user `odoo` dengan UID/GID `101`. Perbaiki
+ownership seluruh volume data Odoo dari container yang sedang berjalan:
+
+```bash
+cid=$(docker compose ps -q odoo)
+docker exec --user root "$cid" sh -c \
+  'chown -R 101:101 /var/lib/odoo && \
+   chmod 755 /var/lib/odoo && chmod 700 /var/lib/odoo/sessions'
+```
+
+Verifikasi write access sebagai user Odoo, lalu restart dan cek log:
+
+```bash
+docker exec --user odoo "$cid" sh -c \
+  'touch /var/lib/odoo/sessions/.write-check && \
+   rm /var/lib/odoo/sessions/.write-check'
+docker compose restart odoo
+docker compose logs --since=30s odoo
+```
+
+Gunakan hanya satu mount volume utama berikut pada Compose:
+
+```yaml
+volumes:
+  - saat_odoo_filestore:/var/lib/odoo
+```
+
+Jangan menambahkan mount terpisah ke `/var/lib/odoo/session` (singular).
+Path yang dipakai Odoo adalah `/var/lib/odoo/sessions` (plural). Jangan
+menggunakan `chmod 777`; cukup berikan ownership kepada user Odoo.
+
+## Rencana migrasi Odoo 17 ke Odoo 18
+
+Migrasi major version harus mengubah schema database. Mengganti image secara
+langsung dari `odoo:17.0` ke `odoo:18.0` **bukan** prosedur migrasi dan dapat
+menyebabkan error seperti `column res_lang.short_time_format does not exist`.
+Compose harus tetap menggunakan `odoo:17.0` sampai database selesai dimigrasi.
+
+### 1. Persiapan dan backup
+
+Pastikan `.env` terisi dan jangan commit file tersebut. Hentikan penulisan data,
+lalu buat backup database dan filestore:
+
+```bash
+set -a && source .env && set +a
+backup_dir="backups/odoo17-$(date +%Y%m%d-%H%M%S)"
+mkdir -p "$backup_dir"
+docker compose exec -T db pg_dump -U "$POSTGRES_USER" -d "$POSTGRES_DB" -Fc \
+  > "$backup_dir/database.dump"
+volume=$(docker inspect saat-odoo --format '{{range .Mounts}}{{if eq .Destination "/var/lib/odoo"}}{{.Name}}{{end}}{{end}}')
+docker run --rm -v "$volume:/source:ro" -v "$PWD/$backup_dir:/backup" alpine \
+  sh -c 'tar czf /backup/filestore.tar.gz -C /source .'
+```
+
+Validasi backup dengan `pg_restore --list` dari image PostgreSQL 16 dan pastikan
+arsip filestore berisi direktori `filestore/`.
+
+### 2. Migrasi pada salinan
+
+Jangan menguji migrasi pada volume produksi. Restore `database.dump` dan
+`filestore.tar.gz` ke environment staging yang terpisah, lalu gunakan salah
+satu jalur resmi berikut:
+
+- Odoo Upgrade Service untuk database Enterprise.
+- OpenUpgrade dengan branch yang sesuai untuk migrasi Community 17 ke 18.
+
+Migrasikan database terlebih dahulu. Sesuaikan custom addon `saat_invest`
+dengan API, view, security, dan dependency Odoo 18, lalu install/upgrade addon
+di database staging hasil migrasi.
+
+### 3. Validasi staging
+
+Uji login, menu saham, create/update/delete transaksi, kalkulasi portofolio,
+cron harga pasar, attachment/filestore, dan seluruh endpoint JSON-RPC yang
+dipakai Flutter. Periksa log untuk `ERROR`, `Traceback`, `UndefinedColumn`, dan
+`PermissionError`.
+
+### 4. Cutover produksi
+
+Setelah staging lulus, hentikan Odoo 17, buat backup final, restore atau jalankan
+migrasi pada database produksi sesuai prosedur tool migrasi, kemudian ubah:
+
+```yaml
+image: odoo:18.0
+```
+
+Pastikan ownership volume sesuai user Odoo 18 sebelum start, jalankan
+`docker compose up -d`, dan ulangi seluruh validasi staging.
+
+### 5. Rollback
+
+Jika migrasi gagal, jangan menjalankan Odoo 17 pada database yang sudah sebagian
+dimigrasi. Hentikan stack, restore database dan filestore dari backup Odoo 17
+ke volume/database terpisah, ubah image kembali ke `odoo:17.0`, lalu validasi
+aplikasi sebelum cutover ulang.
+
 ## API untuk Flutter (via JSON-RPC `execute_kw`)
 Semua melalui `POST /jsonrpc` dengan `{service:'object', method:'execute_kw'}`.
 Login: `common.authenticate(db, user, pass)` → `uid`.
