To run a keycloak migrate from wildfly to quarkus project, back up your database first. Next, move your old setup files into the new flat property format. Many teams rush this upgrade to keep their login servers supported. During the move, engineers often grant broad admin roles to test the new server. Broad roles let too many users read sensitive data or run risky commands.
How to plan a keycloak migrate from wildfly to quarkus setup
The old server ran on a heavy Java runtime with complex XML files. The new Quarkus engine compiles settings at build time for faster startup. You do not edit deep XML trees anymore. Instead, you set up the server using simple key and value pairs.
Start the move by taking a full snapshot of your identity database. The new server reads the existing schema and updates the tables on startup. You must place your database driver into the new provider folder before launch. Then, set your database URL and login keys in the main settings file.
Custom themes and extensions need extra care during the move. Old modules must move into the new providers directory. You run a build step so the server indexes these files first. After the build step finishes, you start the server and check the logs.
Network rules also change in the new runtime. You must set up hostnames, TLS keys, and reverse header rules in plain text. Test your login flows in a staging space before you switch production traffic. Check that every app still reads user tokens and group claims without errors.
What the upgrade solves and what it leaves open
Moving to the Quarkus distribution makes your identity server much lighter and faster. It cuts memory use and speeds up container boot times in cloud clusters. Your team also gets a simpler way to manage server settings across stages.
Still, an identity server upgrade only handles who can log in to your systems. Keycloak checks user passwords and issues tokens with group and role names. Once a user or tool holds a valid token, Keycloak steps out of the way.

This leaves a big gap during daily operations and database work. Suppose an engineer logs in with a valid role to fix a bug. Keycloak cannot see the SQL queries or shell commands that run next. It cannot stop someone from dropping a table or reading raw customer records.
Even with strict roles, shared admin accounts often stay active after migration tests end. Teams need controls that inspect every query and command in flight. You also need data masking that rewrites emails, phone numbers, and card numbers in results. Identity checks alone cannot give you command-level logs or field-level data masking.
How to test roles and claims after the switch
After the new server boots, review every realm and client role right away. Remove any temporary admin roles that your team used during the upgrade. Check that service accounts only hold the exact scopes they need to run.
Have a test user log in to each connected app and database tool. Inspect the token payload to confirm that group names match your old setup. Watch the server logs for failed login attempts or missing provider warnings. Once every check passes, you can point your main DNS record to the new cluster.
Govern statements and responses across databases and APIs
Good config and scoped roles are needed setup. They do not check single queries in flight or mask sensitive fields in returned rows. Across Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, and internal HTTP endpoints, hoop.dev sits inline in the protocol beside each supported service as an open-source proxy, a sidecar for your database or API. For every query or command an AI agent or engineer runs against production, hoop.dev decides to pass, mask, block, or hold it for human approval.
First, hoop.dev guardrails block banned queries before they run or hold risky ones for review, and hoop.dev data masking rewrites matched sensitive values in responses in memory. Furthermore, hoop.dev holds SOC 2 Type II and is open source on GitHub.
Frequently asked questions
Does the database upgrade happen on its own during startup?
Yes, the new server updates the database schema when it boots up. Always save a full database backup before you run the new version.
Do users need to reset their passwords after the move?
No, user accounts and password hashes stay inside your existing database tables. Users can log in with their current passwords as soon as traffic switches over.
What happens to custom Java extensions from the old server?
Most standard extensions still work if you drop the jar files into the providers folder. Extensions that used internal Wildfly APIs must be rewritten for the new runtime.
