database text format inconsistencies

When you create the moodle database, use something like this:

mysql > create database moodle collate utf8mb4_unicode_ci;

And when you set up the config.php file, make sure the line "dbcollation" mentions the same text format (utf8mb4_unicode_ci).

To check what text collation you used, in mysql, type:

SELECT @@character_set_database, @@collation_database;

If you don't do this, you might have to edit  

    vi /var/www/html/moodle/lib/dml/mysqli_native_moodle_database.php

and change line 196 to read

        $sql = "SELECT @@storage_engine engine";

instead of

        $sql = "SELECT @@default_storage_engine engine";

could not find course/ could not find top level course/ could not find course category

Could not find course category If you get this error (could not find course category) this basically means the course/s that exist don't have categories in the category table. Look at the mdl_course table in mysql. Column 2 is the course category. Every course listed (per row) must have a category identified in the table mdl_course_categories . For example, if you have this as your data (1, 0 , 0, "course name", " course name ", "", "summary" , 0, "site", 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, "", "", "", 1606214720, 1606215795, 0, 0, 0, 1606215383); You see the course category is zero . But there is a course category number one in the mdl_course_categories  table: |  1 | Miscellaneous | NULL     | NULL        |                 0 |      0 |     10000 |           0 |       1 |          1 |   1606214720 | ...

migrating moodle from one server to another

When you migrate moodle from one server to another, you have to take a copy of three things and make certain changes. There are some caveats however which I will mention here. Moodle has three main parts, the app itself, the database, and the uploads and cache data repository. We are going to assume that the following paths are used by Moodle: /var/www/moodle/ - the app itself, containing folders like "admin, analytics, auth, availability, badges..." and importantly, the config.php file /var/www/moodle_data/ - the app cache data and uploads, containing the folders "cache, diag, filedir, lang, localcache, lock, muc, sessions, temp, trashdir" Let's assume for this example that your database is called moodle , your database username is moodle , and your password is abc123 . Let's also assume your target server allows you to upload files as root over ssh/scp. We divide the instructions up into source server and target server/new server. Let's assume you...
