This flow shows moving a WordPress site from one environment to another by exporting, transferring, importing, updating settings, and testing.

Execution Sample

Wordpress

<?php
// Export DB
// Transfer files
// Import DB
// Update wp-config.php
// Search and replace URLs
?>

Basic steps to migrate a WordPress site: export database, move files, import database, update config, and fix URLs.

Execution Table

Step	Action	Details	Result
1	Export Files & DB	Backup wp-content and export database SQL	Files and DB ready for transfer
2	Transfer Data	Upload files and DB dump to new server	Data available on new environment
3	Import Database	Run SQL import on new DB	Database restored with old data
4	Update Config	Edit wp-config.php with new DB credentials	WordPress connects to new DB
5	Search & Replace URLs	Replace old URLs with new site URLs in DB	Links and media point correctly
6	Test Site	Open site in browser, check pages and media	Site works as expected
7	Fix Issues	Resolve broken links or permissions	Site fully functional
8	Exit	Migration complete	Site live on new environment

💡 Migration ends after testing and fixing issues to ensure site works on new environment

Variable Tracker

Variable	Start	After Export	After Transfer	After Import	After Config Update	After URL Replace	Final

Database	On Dev Server	Exported SQL	Transferred SQL	Imported	Connected	URLs Updated	Ready
Config	Old DB Credentials	Unchanged	Unchanged	Unchanged	New DB Credentials	Unchanged	Updated

Key Moments - 3 Insights

Why do we need to replace URLs in the database after migration?

Because the site URL changes between environments, and old URLs in the database would point to the wrong location, causing broken links or missing images. See step 5 in execution_table.

What happens if wp-config.php is not updated with new database credentials?

WordPress cannot connect to the database, so the site will not load properly. This is shown in step 4 where updating config is necessary.

Why test the site after migration before going live?

To catch any broken links, missing files, or permission issues that might have occurred during transfer. Step 6 and 7 cover testing and fixing.

Visual Quiz - 3 Questions

Look at the execution_table, what is the result after step 3 (Import Database)?

A Database restored with old data

B Files backed up

C Site live on new environment

D URLs replaced

💡 Hint

Check the 'Result' column for step 3 in execution_table

At which step do we update the wp-config.php file?

A Step 2

B Step 5

C Step 4

D Step 6

💡 Hint

Look for 'Update Config' action in execution_table

If we skip step 5 (Search & Replace URLs), what problem will most likely occur?

A Database import will fail

B Site URLs will point to old environment causing broken links

C Files will not transfer

D wp-config.php will have wrong credentials

💡 Hint

Refer to key_moments about URL replacement importance

Concept Snapshot

Migration between environments in WordPress:
1. Export files and database from source.
2. Transfer files and DB dump to target.
3. Import database on target.
4. Update wp-config.php with new DB info.
5. Replace old URLs in DB with new site URLs.
6. Test site and fix issues before going live.

Full Transcript

Migrating a WordPress site means moving it from one environment to another, like from development to production. First, you export the site files and database. Then, you transfer these to the new environment. Next, you import the database and update the wp-config.php file with the new database credentials. Because URLs in the database still point to the old site, you must replace them with the new URLs. Finally, you test the site to ensure everything works and fix any issues found. This process ensures the site runs smoothly in the new environment.

Practice

1. What is the main purpose of migrating a WordPress site between environments?

easy

A. To move the site safely from one place to another

B. To change the site's theme permanently

C. To delete all plugins and start fresh

D. To increase the site's loading speed automatically

Solution

1. Step 1: Understand migration meaning

   Migration means moving a site from one environment (like local or staging) to another (like live).

2. Step 2: Identify the main goal

   The goal is to move the site safely without losing data or breaking it.

3. Final Answer:

   To move the site safely from one place to another -> Option A

4. Quick Check:

   Migration = safe site move [OK]

Hint: Migration means moving site safely between places [OK]

Common Mistakes:

• Thinking migration changes themes automatically
• Assuming migration deletes plugins
• Believing migration speeds up site by itself

2. Which of the following is the correct way to update URLs after migrating a WordPress site?

easy

A. Change URLs only in the wp-config.php file

B. Manually edit URLs in the database using a search and replace tool

C. Leave URLs as they are; WordPress updates them automatically

D. Delete the .htaccess file to reset URLs

Solution

1. Step 1: Recognize URL update necessity

   After migration, URLs often need updating to match the new domain or path.

2. Step 2: Choose the correct method

   Using a search and replace tool on the database is the proper way to update all URLs safely.

3. Final Answer:

   Manually edit URLs in the database using a search and replace tool -> Option B

4. Quick Check:

   Update URLs with search and replace [OK]

Hint: Use search and replace tool on database URLs [OK]

Common Mistakes:

• Thinking wp-config.php controls URLs
• Assuming WordPress auto-updates URLs always
• Deleting .htaccess breaks site rules

3. After migrating a WordPress site manually, which step ensures the media files are correctly moved?

medium

A. Change the site URL in wp-config.php

B. Only export the database; media files move automatically

C. Reinstall all plugins to restore media files

D. Copy the wp-content/uploads folder to the new environment

Solution

1. Step 1: Identify media file location

   Media files are stored in the wp-content/uploads folder in WordPress.

2. Step 2: Ensure media files move

   Copying this folder to the new environment keeps all media intact.

3. Final Answer:

   Copy the wp-content/uploads folder to the new environment -> Option D

4. Quick Check:

   Media files = wp-content/uploads copy [OK]

Hint: Copy uploads folder to move media files [OK]

Common Mistakes:

• Thinking media files move with database only
• Reinstalling plugins does not restore media
• Changing wp-config.php does not move files

4. You migrated your WordPress site but see broken links and missing images. What is the most likely cause?

medium

A. You forgot to update URLs in the database after migration

B. You copied the uploads folder twice

C. You changed the site URL in the wp-config.php file correctly

D. You used a plugin to migrate the site

Solution

1. Step 1: Analyze symptoms

   Broken links and missing images usually mean URLs still point to the old site.

2. Step 2: Identify cause

   If URLs in the database are not updated, links break after migration.

3. Final Answer:

   You forgot to update URLs in the database after migration -> Option A

4. Quick Check:

   Broken links = URLs not updated [OK]

Hint: Broken links? Check database URLs first [OK]

Common Mistakes:

• Assuming copying uploads twice fixes links
• Thinking changing wp-config.php fixes broken links
• Believing plugins always fix URL issues automatically

5. You want to migrate a WordPress site from a local environment to a live server. Which sequence of steps is best practice?

hard

A. Install WordPress fresh on live, then copy themes and plugins manually

B. Copy wp-content folder only, then change site URL in wp-config.php

C. Export database, copy wp-content folder, update wp-config.php, replace URLs in database

D. Export database and import it on live, no need to copy files

Solution

1. Step 1: Export database and copy files

   Exporting the database and copying the wp-content folder moves content and media.

2. Step 2: Update configuration and URLs

   Update wp-config.php for database access and replace URLs in the database to match live site.

3. Final Answer:

   Export database, copy wp-content folder, update wp-config.php, replace URLs in database -> Option C

4. Quick Check:

   Full migration = DB export + files + config + URL update [OK]

Hint: Export DB, copy files, update config and URLs [OK]

Common Mistakes:

• Copying files without exporting database
• Changing wp-config.php without URL updates
• Installing fresh WordPress loses content
