<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>To simplify the migration process, we think it would be great to provide a three-step form:</p>
<h4>Step 1: Configure “Media: Acquia DAM” media types mapping:</h4>
<ul>
<li>Display the list of all Media: Acquia DAM media types only (excluding Acquia DAM Media Types), as this form is primarily meant to migrate source plugins of existing media types provided by the Media: Acquia DAM.</li>
<li>Listing of media types should be Sort by the number of media items (highest → lowest), so users can focus on relevant media types.</li>
<li>Allow configuration for only those media types with more than 0 media items. If a media type has 0 media items, we are enforcing those media types for deletion, instead of keeping an unused legacy Media: Acquia DAM media type.
</li>
<li>Set Sync as the default method for handling media files, since their existing Media: Acquia DAM media types are already using this method only. Hence, we should default to this.</li>
<li>Auto-select the target source type if it matches our module's provided media types. (This is already working as expected today).</li>
<li>Restrict target source options based on media type relevance:</li>
<li>
<ul>
<li>The target source types for Acquia DAM media types should be limited and it should be based on matching file extensions for each media type, so that we can limit / filter the options. For Ex: If Media Acquia DAM image media type supports png, jpeg file extensions only, then we should show only those Acquia DAM media types, which supports png, jpeg file extensions only. </li>
</ul>
</li>
</ul>
<h4>Step 2: Configure “Acquia DAM” media types for deletion:</h4>
<ul>
<li>Users will see the list of all Media Types provided by Acquia DAM module with a delete checkbox next to each. They can opt to delete unnecessary media types during migration.
</li>
<li>We are proposing Auto-select delete checkboxes, mainly for the following media types: Acquia DAM: Audio, Acquia DAM: Video, Acquia DAM: Image, and Acquia DAM: Document, since corresponding existing media types (provided by Media: Acquia DAM module) will exist post-migration for media types having media items more then 0. This helps avoid duplicates or redundant media types.</li>
<li>If a user unchecks an auto-selected delete option, a warning popup will appear, recommending deletion for clarity.
</li>
<li>Newly added media types without a direct equivalent will not have their delete checkboxes auto-selected or prompt warnings upon unchecking.</li>
<li>A Back button will allow users to return to Step 1 for modifications and also Next Button for proceeding to Step 3.</li>
</ul>
<h4>Step 3: Migration Summary</h4>
<ul>
<li>Display a summary of migration configurations:</li>
<li>
<ul>
<li>Which media types will be deleted.</li>
<li>Source Plugin mapping details.</li>
<li>Any label changes applied to media types (provided by Media: Acquia DAM module).</li>
<li>Method selected to handle media types (i.e Embed Or Sync method).</li>
</ul>
</li>
<li>Provide:</li>
<li>
<ul>
<li>Back button (to return to Step 2)</li>
<li>Save button (to store configuration changes for later migration).</li>
<li>Save & Migrate button (to apply changes and initiate migration immediately)</li>
</ul>
</li>
</ul>
