 This guide will help you migrate from Config V1 to Config V2.
 
+## What is Config V2?
+
+Config V2 is the next generation of ConfigCat. It comes with a new dashboard, API, SDKs, and features. It's not backward compatible with Config V1. Read more about the new features in the [Config V2 Overview](advanced/config-v2).
+
+## A few things to consider before migration
+
+- Config V2 and V1 are completely separate. They don't affect each other in any way. You can use them side by side.
+- Every newly created config is a V2 config.
+- You can migrate your V1 configs to V2. That will mean that a V1 and a V2 version of your config will be available at the same time. The V2 version will have a new SDK key for each environment.
+- There is no automatic sync between the V1 and V2 configs. You have to manually update the V2 config if you make changes to the V1 config and vice versa.
+- Once started it's recommended to migrate your V1 configs to V2 as quickly as possible to avoid confusion.
+- There is no pressure to migrate. You can stay on V1 for a long time.

+
+## New features
+
+### AND conditions
+
+With AND conditions, you can create more complex targeting rule sets for your feature flags. You can add multiple conditions to a targeting rule and they will be evaluated as a logical AND.
+
+### New comparators
+
+With the new comparators, you can create date based targeting rules and schedule releases, compare arrays etc.
+
+- New text and sensitive text comparators: EQUALS, NOT EQUALS, STARTS WITH ANY OF, ENDS WITH ANY OF, NOT STARTS WITH ANY OF, NOT ENDS WITH ANY OF.
+- New array comparators: ARRAY CONTAINS ANY OF, ARRAY NOT CONTAINS ANY OF.
+- New date comparators: BEFORE, AFTER.
+
+### Prerequisite flags
+
+With prerequisite flags, you can create feature flags that depend on other feature flags. Prerequisite feature flags are particularly useful for managing complex feature dependencies and ensuring a smooth user experience during feature rollouts.
+
+### Comparison value hints
+
+With comparison value hints, you can add hints to your comparison values. This way you can add a description to your comparison value list items that helps you remember what they are for.
+
+### Percentage options for targeting rules
+
+You can add percentage options to your targeting rules. This is useful if you want to create percentage options based on your user attributes.
+
+### Custom percentage attributes
+
+With custom percentage attributes, you can create percentage options based on custom attributes. This way you can create percentage options based on any of your user attributes.
