+# Legacy data migration
+
+## Introduction
+
+You can migrate your blocks & pages from the 4.x version to the 5.x version of the plugin.
+To do so, you need to follow the steps below.
+
+## Steps
+
+1. Create new CSV files with blocks & pages data in the 4.x format.  
+See an example in [block_legacy.csv](block_legacy.csv) or [page_legacy.csv](page_legacy.csv).
+2. Install the 5.x version of the plugin.
+3. Go to the console and run the following command:
+```bash
+bin/console cms:import:csv page_legacy {file_path}.csv
+bin/console cms:import:csv block_legacy {file_path}.csv
+```
+
+## Info about legacy CSV files columns
+
+### Blocks
+
+- **code** - block code.
+- **type** - it will be ignored.
+- **name_LOCALE** - block name. First occurrence of its column is the default name for the block. 
+For each locale, there will be created a Heading content element.
+- **content_LOCALE** - block content. For each locale, there will be created a Textarea content element.
+- **sections** - it will be converted to the block's collections.
+- **channels** - block channels.
+- **products** - block products. There will be created Products grid content element.
+- **image_LOCALE** - block image. For each locale, there will be created a Single media content element.
+- **slug_LOCALE** - it will be ignored.
+
+### Pages
+
+- **code** - page code.
+- **sections** - it will be converted to the page's collections.
+- **channels** - page channels.
+- **products** - page products. There will be created Products grid content element.
+- **slug_LOCALE** - page slug.
+- **name_LOCALE** - page name. First occurrence of its column is the default name for the page.
+For each locale, there will be created a Heading content element.
+- **image_LOCALE** - page image. For each locale, there will be created a Single media content element.
+- **meta_keywords_LOCALE** - page meta keywords.
+- **meta_description_LOCALE** - page meta description.
+- **content_LOCALE** - page content. For each locale, there will be created a Textarea content element.
+- **breadcrumb_LOCALE** - it will be ignored.
+- **name_when_linked_LOCALE** - for each locale, there will be created a teaser title.
+- **description_when_linked_LOCALE** - for each locale, there will be created a teaser content.
