SQL Server Identity Transformation — Implementation Companion

The executable counterpart to the narrative series: runbooks, audits and validation for each step

The Implementation Companion turns the SQL Server Identity Transformation narrative into runbooks. The narrative explains why each step happens and in what order; each book here covers how to carry it out, what the tooling produces, and how to check the result. Read Book 01 first: it sets out the prerequisites, the evidence model and the run order the other books assume.

Book Title Narrative counterpart
01 Prerequisites and using this companion Book 01
02 Estate discovery and the consolidation gate Book 02
03 The authentication audit Book 03
04 Arc deployment and the instance identity (managed identity on SQL Server 2025; app registration plus certificate on 2022) Book 04
05 Login migration and parallel-run validation Book 05
06 NTLM detection and remediation Book 06
07 Groups, administrative units and the Conditional Access perimeter Book 07
08 The application chain and connection-string migration Book 08
09 Continuous monitoring and the closure record Book 09
10 Certificate discovery for SQL Server’s ADCS dependencies Book 10

The narrative’s epilogue, Book 11 (the platform question), is a decision framework rather than a procedure, so it has no implementation book.
