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
Files	On Dev Server	Backed up	Uploaded to New Server	Extracted	Unchanged	Unchanged	Ready
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.
