-Paweł, dla DBA najbardziej ryzykowna jest migracja SQL Server Failover Cluster Instance (FCI), bo oprócz samych baz musisz przenieść również warstwę Windows Cluster, storage, konta serwisowe, zależności aplikacyjne i procedury HA/DR. W waszych ostatnich projektach migracyjnych przewijały się m.in. kwestie konfiguracji dysków, backupów natywnych SQL, kont serwisowych, AG oraz szczegółowego planu testów i rollbacku. citeturn3search17turn3search16turn3search19

+# 1. Discovery Phase
 
-SQL Agent
- SQL Agent Jobs
- Schedules
- Operators
- Alerts
- Proxies
+## 1.1 Existing Windows Cluster
 
-Joby SQL Agent są często ważniejsze od samych baz danych.
+### Cluster Inventory
 
-Integracje
- Linked Servers
- Linked Login Mappings
- SSIS Packages

-Podczas waszych migracji pojawiał się temat osobnych dysków danych, logów, backupów i swap.
+### Cluster Validation
 
-Performance
- IOPS Validation
- Latency Validation
- Throughput Validation
-SQL Installation
-Instalacja
- Install FCI Node1
- Add Node2
- Install same CU
- Enable TCP/IP
-Konfiguracja

+```
 
-W waszych planach migracyjnych DBCC CHECKDB i test restore są obowiązkowe przed produkcją.

-Faza 6 - Rollback Criteria
+## SQL Instance
 
-Rollback musi być zdefiniowany przed migracją.
+```sql
+SELECT @@VERSION;
+```
 
-Uruchamiamy rollback gdy:
+- [ ] SQL Version
+- [ ] SQL Edition
+- [ ] SQL CU/SP Level
+- [ ] Instance Name
+- [ ] Cluster Name
+- [ ] Collation
+- [ ] Authentication Mode
+- [ ] Max Server Memory
+- [ ] MaxDOP
+- [ ] Cost Threshold
+- [ ] TempDB Configuration
+- [ ] Startup Parameters
+- [ ] Trace Flags
 
- Aplikacja nie działa
- Utrata danych
- Krytyczne błędy logowania
- Niedziałające integracje
- Niedziałający failover
+---
 
-W waszych projektach rollback polegał na:
+# 3. Database Inventory
 
-przełączeniu aplikacji z powrotem na stary serwer,
-wyłączeniu nowych jobów,
-ponownym uruchomieniu jobów źródłowych,
-walidacji działania aplikacji.
-Najczęściej zapominane elementy

-Jeżeli migrujesz konkretnie FCI SQL 2016/2019/2022 → nowy FCI SQL 2022, mogę przygotować jeszcze bardziej szczegółowy runbook produkcyjny w formacie Markdown/Org-mode z dokładnym harmonogramem T-30, T-7, T-1, T0, T+1 oraz gotowymi skryptami SQL i PowerShell do każdego kroku.
