TheMostFabulousMagentoMigrationChecklist

Ummm name says it all TheMostFabulousMagentoMigrationChecklist. This is a checklist you can use for migrating Magento to a different host.

Match Service Versions

Just do it: PHP, MySQL, Redis, Varnish, ElasticSearch, OpenSearch, RabbitMQ

1. PHP

   php -v
   

2. MySQL

   mysql --version
   

3. Redis

   redis-cli --version
   

4. Varnish

   varnishstat -V
   

5. ElasticSearch

6. OpenSearch Version check:

   curl -X GET http://localhost:9200 -u 'admin:admin'
   

   Installation:

   curl -o- https://artifacts.opensearch.org/publickeys/opensearch.pgp | sudo apt-key add -
   echo "deb https://artifacts.opensearch.org/releases/bundle/opensearch/2.x/apt stable main" | sudo tee           /etc/apt/sources.list.d/opensearch-2.x.list
   sudo apt update
   sudo apt list -a opensearch
   sudo apt -y install opensearch=2.5.0
   sudo systemctl enable opensearch
   nano /etc/opensearch/opensearch.yml
       #change 'plugins.security.ssl.http.enabled' true to false
   sudo systemctl start opensearch
   

   Set Magento to use OpenSearch under stores->configuration->catalog->catalog (default HTTP Auth is admin/admin)
