The command sequence is:

# Get latest codebase
git pull
git checkout <branch>

# Check for any new configuration
./drush cex

# Apply codebase changes to environment
./drush updatedb
./drush cim

Once update, update the Solr config with:

Next, add the missing custom blocks:

1. Login as admin.
2. Structure > Block Layout from main menu.
3. Remove: "Mega Menu Icon", "Solr Search Block" and "All Rights Reserved" blocks.
4. Create three new custom blocks:
   1. Custom Block Library tab.
   2. Add Custom Block button.
   3. Content block type.
   4. Create the Mega Menu Icon and Solr Search Footer blocks, making sure text format is Full HTML.

<!-- Mega Menu Icon -->
<a id="menu-toggle-icon" class="toggle mega-menu-toggle-icon" title="Menu" href="#open-menu">
  <span class="icon"></span><span class="label">Menu</span>
</a>

<!-- Solr Search Footer -->
<div class="search-block-form contextual-region block block-search container-inline" data-drupal-selector="search-block-form" role="search">
    <form action="/en/solr/search" method="get" accept-charset="UTF-8">
        <div class="js-form-item form-item js-form-type-search form-type-search js-form-item-keys form-item-keys form-no-label">     
            <label for="edit-keys" class="visually-hidden">What are you looking for today?</label>
            <input title="Enter the terms you wish to search for." data-drupal-selector="edit-keys" type="search" name="search_api_fulltext" value="" size="15" maxlength="128" class="form-search" placeholder="What are you looking for today?">
        </div>
        <div data-drupal-selector="edit-actions" class="form-actions js-form-wrapper form-wrapper">
            <button class="search-form__submit box--purple box--arrow button js-form-submit form-submit" data-twig-suggestion="search_results_submit" data-drupal-selector="edit-submit" type="submit" value="Search">Search</button>
        </div>
    </form>
</div>

Next, click Translate on the Solr Search Footer Edit menu and add the following for the French search:

<!-- Solr Search Footer -->
<div class="search-block-form contextual-region block block-search container-inline" data-drupal-selector="search-block-form" role="search">
    <form action="/fr/solr/search" method="get" accept-charset="UTF-8">
        <div class="js-form-item form-item js-form-type-search form-type-search js-form-item-keys form-item-keys form-no-label">     
            <label for="edit-keys" class="visually-hidden">Qu'est-ce que vous recherchez aujourd'hui?</label>
            <input title="Saisissez les termes que vous souhaitez rechercher." data-drupal-selector="edit-keys" type="search" name="search_api_fulltext" value="" size="15" maxlength="128" class="form-search" placeholder="Qu'est-ce que vous recherchez aujourd'hui?">
        </div>
        <div data-drupal-selector="edit-actions" class="form-actions js-form-wrapper form-wrapper">
            <button class="search-form__submit box--purple box--arrow button js-form-submit form-submit" data-twig-suggestion="search_results_submit" data-drupal-selector="edit-submit" type="submit" value="Chercher">Chercher</button>
        </div>
    </form>
</div>

Finally, go back to the Block Layout screen and place the blocks:

1. Navigation section: Place block.

2. Mega Menu Icon, without Display title.

3. Move it to the third block in the section.

4. Footer section: Place block.

5. Solr Search Block EN, without Display title.

6. Move it to the third block in the section.
