I want to migrate my plugin to the new platform and I generated the skeleton using [https://github.com/elastic/kibana/tree/master/packages/kbn-plugin-generator](https://github.com/elastic/kibana/tree/master/packages/kbn-plugin-generator). I have encountered two anomalies: - On 7.7.0, after inserting `visualizations` in the `requiredPlugins` entry in `kibana.json`, visualizations does not work, resulting in "undefined" (I tried to use it in `plugin.ts`, both in `setup` and in `start`). The same plugin instead works on 7.8.0. - On 7.8.0, after inserting `visualizations` in the `requiredPlugins` entry in `kibana.json`, this works, I can do everything, only that the visualization type "region\_map" is not in the list of all visualizations (`visualizations.all ()`), this should because of the "region\_map" migration to the New Platform occurred in 7.9.0 (see [link](https://github.com/elastic/kibana/pull/64272)). The question then is: can I import the legacy **"visualizations" plugin** into a Kibana New Platform plugin? Thanks, I remain available for clarification ---

We've been careful to keep the new plugins free of any legacy code, so it's possible for legacy plugins to access new plugins (via importing from `ui/new_platform`) but not the other way around. You can use the services in `ui/new_platform` to emulate a new plugin from within a legacy plugin, but it requires some manual steps: - You should load your plugin via a "hacks" uiExport to ensure your plugin is always loaded - You must run the "setup" and "start" functions of your plugin yourself - There are some limitations, for example, while legacy plugins can "depend on" any other new plugin via the `ui/new_platform` exports, these dependencies are not programmatically enforced. So you must handle the case where your dependency has been disabled. For custom development, this may not be a concern, but if your plugin is shared with others, it may be. The [vis\_type\_metric plugin on the 7.7 branch](https://github.com/elastic/kibana/blob/7.7/src/legacy/core_plugins/vis_type_metric/public/legacy.ts) is a good example of this pattern. You'll notice in the index.js file there is a "hack" that points to the "public/legacy" file. This file handles setting up and starting the plugin manually. The other option would be to wait for the 7.9 release in which all of the visualizations have been migrated. I don't have any timeline on when this will be released, but you can start developing against the 7.9 branch today. ---
