# How To Update An Older Plugin

This topic summarizes what to do if you have a Plugin developed with an older Designer and you want to make it work with the newer Designer version.

- If the new release of Designer has an API version (see section Plugin and Versioning Guidelines), which is compatible with the older API Version, then you do not need to change anything.

- If the version of the new Designer API is not compatible with the API version you used to build your plugin, you need to recompile your plugin (see topic Updating a Visual Studio Plugin Project).

  1. If it compiles without error, you only need update the Target API in the plugin.config to the new API version (since nothing has changed in the your plugin code, there is no need to change the plugin version).

  2. If the plugin does not compile, you will need to fix the bugs, recompile and then update the API and Plugin Version accordingly.
