Migration Guide: From v1 to v2
How to Migrate from Traefik v1 to Traefik v2. {: .subtitle }
The version 2 of Traefik introduces a number of breaking changes, which require one to update their configuration when they migrate from v1 to v2. The goal of this page is to recapitulate all of these changes, and in particular to give examples, feature by feature, of how the configuration looked like in v1, and how it now looks like in v2.
!!! info "Migration Helper"
We created a tool to help during the migration: [traefik-migration-tool](https://github.com/containous/traefik-migration-tool)
This tool allows to:
- convert `Ingress` to Traefik `IngressRoute` resources.
- convert `acme.json` file from v1 to v2 format.
- migrate the static configuration contained in the file `traefik.toml` to a Traefik v2 file.
Frontends and Backends Are Dead...
... Long Live Routers, Middlewares, and Services
During the transition from v1 to v2, a number of internal pieces and components of Traefik were rewritten and reorganized. As such, the combination of core notions such as frontends and backends has been replaced with the combination of routers, services, and middlewares.
Typically, a router replaces a frontend, and a service assumes the role of a backend, with each router referring to a service. However, even though a backend was in charge of applying any desired modification on the fly to the incoming request, the router defers that responsibility to another component. Instead, a dedicated middleware is now defined for each kind of such modification. Then any router can refer to an instance of the wanted middleware.
!!! example "One frontend with basic auth and one backend, become one router, one service, and one basic auth middleware."

TLS Configuration Is Now Dynamic, per Router.
TLS parameters used to be specified in the static configuration, as an entryPoint field. With Traefik v2, a new dynamic TLS section at the root contains all the desired TLS configurations. Then, a router's TLS field can refer to one of the TLS configurations defined at the root, hence defining the TLS configuration for that router.

HTTP to HTTPS Redirection Is Now Configured on Routers
Previously on Traefik v1, the redirection was applied on an entry point or on a frontend. With Traefik v2 it is applied on a Router.
To apply a redirection, one of the redirect middlewares, RedirectRegex or RedirectScheme, has to be configured and added to the router middlewares list.

Strip and Rewrite Path Prefixes
With the new core notions of v2 (introduced earlier in the section
"Frontends and Backends Are Dead... Long Live Routers, Middlewares, and Services"),
transforming the URL path prefix of incoming requests is configured with middlewares,
after the routing step with router rule PathPrefix.
Use Case: Incoming requests to http://company.org/admin are forwarded to the webapplication "admin",
with the path /admin stripped, e.g. to http://<IP>:<port>/. In this case, you must:
- First, configure a router named
adminwith a rule matching at least the path prefix with thePathPrefixkeyword, - Then, define a middlware of type
stripprefix, which remove the prefix/admin, associated to the routeradmin.

??? question "What About Other Path Transformations?"
Instead of removing the path prefix with the [`stripprefix` middleware](../../middlewares/stripprefix/), you can also:
* Add a path prefix with the [`addprefix` middleware](../../middlewares/addprefix/)
* Replace the complete path of the request with the [`replacepath` middleware](../../middlewares/replacepath/)
* ReplaceRewrite path using Regexp with the [`replacepathregex` middleware](../../middlewares/replacepathregex/)
* And a lot more on the [`middlewares` page](../../middlewares/overview/)

Traefik Logs
In the v2, all the log configuration remains in the static part but are unified under a log section.
There is no more log configuration at the root level.

Tracing
Traefik v2 retains OpenTracing support. The backend root option from the v1 is gone, you just have to set your tracing configuration.

```
Metrics
The v2 retains metrics tools and allows metrics to be configured for the entrypoints and/or services. For a basic configuration, the metrics configuration remains the same.
!!! example "Simple Prometheus metrics configuration"
!!! info "v1"
```toml tab="File (TOML)"
# static configuration
[metrics.prometheus]
buckets = [0.1,0.3,1.2,5.0]
entryPoint = "traefik"
```
```bash tab="CLI"
--metrics.prometheus.buckets=[0.1,0.3,1.2,5.0]
--metrics.prometheus.entrypoint="traefik"
```
!!! info "v2"
```toml tab="File (TOML)"
# static configuration
[metrics.prometheus]
buckets = [0.1,0.3,1.2,5.0]
entryPoint = "metrics"
```
```yaml tab="File (YAML)"
# static configuration

```
```bash tab="CLI"
--metrics.prometheus.buckets=[0.1,0.3,1.2,5.0]
--metrics.prometheus.entrypoint="metrics"
```

Dashboard
You need to activate the API to access the dashboard. As the dashboard access is now secured by default you can either:
- define a specific router with the
api@internalservice and one authentication middleware like the following example - or use the unsecure option of the API
!!! info "Dashboard with k8s and dedicated router"
As `api@internal` is not a Kubernetes service, you have to use the file provider or the `insecure` API option.

Some Tips You Should Know
- Different sources of static configuration (file, CLI flags, ...) cannot be mixed.
- Now, configuration elements can be referenced between different providers by using the provider namespace notation:
@<provider>. For instance, a router namedmyrouterin a File Provider can refer to a service namedmyservicedefined in Docker Provider with the following notation:myservice@docker. - Middlewares are applied in the same order as their declaration in router.
