Need some basic help to understand how to upgrade from 7.0 to 7.4? https://liferay.dev/c/message_boards/find_thread?p_l_id=119785294&threadId=121375323 2026-04-06T08:13:20Z 2026-04-06T08:13:20Z Aurelien Hatri https://liferay.dev/c/message_boards/find_message?p_l_id=119785294&messageId=121378405 2022-03-16T18:35:05Z 2022-03-16T09:34:43Z

<p>I confirmed it's really painful to learn liferay and in the same time to migrate &quot;an old project&quot;.</p> <p>So to give some feedbacks: I finally decided to start from scratch. I made on assumption on some properties to generate the theme to extend and I iterated from it with a lot of copy and paste from the orginal source code.</p> <p>So far I have two issues :</p> <p> <strong>First)</strong></p> <p>The store for the document is DB. As I said I dumped the DB, create a new one, and I played the &quot;portal-tools-db-upgrade-client&quot; on it. I can see my documents but I still have some errors on some pages like : </p> <pre> <code>=&gt; request['theme-display']  [in template &quot;20116#20152#1009391&quot; at line 1, column 26] ---- Tip: It's the final [] step that caused this error, not those before it. ---- Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use &lt;#if myOptionalVar??&gt;when-present&lt;#else&gt;when-missing&lt;/#if&gt;. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)?? ---- ---- FTL stack trace (&quot;~&quot; means nesting-related):     - Failed at: #assign images_folder = request[&quot;them...  [in template &quot;20116#20152#1009391&quot; at line 1, column 1] ----</code></pre> <p>I'm trying to find what is going on but so far I don't have a good lead.</p> <p> </p> <p> <strong>Second)</strong></p> <p>On the pages configuration we have a custom layout. After migration I don't see it anymore, I don't know why.</p> <p> </p> <p>Any helps on the two issues are welcome.</p>

<p>Hello guys !</p> <p>I'm new to liferay and and I'm learning it the hard way.</p> <p>My task is to take 3 maven projects &quot;wars&quot; (two themes and 1 &quot;portlet&quot; form) in 7.0 and to upgrade them in 7.4.</p> <p>So far I succeed to upgrade the database, and to deploy the 3 projects in a 7.4 liferay tomcat bundle (I just replaced in some xml/properties 7.0.0 by 7.4.0).</p> <p>Of course nothing is working properly I have some errors.</p> <p>I'm wondering what is the best way to upgrade the code without trying to correct the errors one by one...</p> <p>So far I tried  :</p> <ul> <li>To use Eclispse LifeRay Upgrade Plan</li> <li>To use generator-liferay-theme</li></ul> <p>But I'm little bit stucked I can't find a way to make them work.</p> <p>Any tips are welcome :)</p> <p>Thanks by advance!</p>
