<p>In seldom cases, Chamilo will generate a series of problems after a migration | 
				
			||||
    . This list is a helper designed mainly by <a href="http://www.beeznest.com/" target="_blank">BeezNest</a> | 
				
			||||
    after its many migration jobs assisting large companies to migrate this critical piece of software.</p> |

<h2><a name="1.Version-specific-issues"></a>1. Version specific issues</h2> | 
				
			||||
<p>Sadly, some issues happen over certain migrations and, so far, the difficulty of | 
				
			||||
    fixing things is still less than the difficulty of knowing exactly what | 
				
			||||
    to do to improve the migration script for all scenarios</p> | 
				
			||||
<h2><a name="2.Documents"></a>2. Documents</h2> | 
				
			||||
    <ul> | 
				
			||||
        <li>The worst that could happen is a change of codification while | 
				
			||||
            migrating from 1.8.5 to 1.8.8.4. Codification problems are nightmares | 
				
			||||
            because you generally get a limited number of characters you can | 
				
			||||
            freely change without affecting already existing files. Scrips can | 
				
			||||
            be made to ananlyse and fix most of the problems, but you will | 
				
			||||
            still need a lot of manual review before you can be sure you | 
				
			||||
            eliminated all problems</li> | 
				
			||||
    </ul> | 
				
			||||
<h2><a name="3.Database-entries"></a>3. Database entries</h2> | 
				
			||||
    <ul> | 
				
			||||
        <li>Some users reported problems with quizzes: when migrating from | 
				
			||||
            1.8.5 to 1.8.8.4, the quiz_question table has a question_order | 
				
			||||
            field filled with 1's. This generates a bug when using exercises | 
				
			||||
            marked random, as you only ever get one question to the test. | 
				
			||||
            <b>Solution:</b> update the question_order field to have sequential numbers.</li> | 
				
			||||
        <li></li> | 
				
			||||
    </ul> |
