What to check
List the versions of your CMS, PHP, database, extensions and theme. Identify maintained components and custom code. The newest release may not be compatible with an older project.
How the update works
Back up files and the database and verify restoration. Update components in a planned sequence on a protected staging copy, fix conflicts and review logs. Keep staging out of search results.
What to test afterwards
Test login, forms, search, cart, payments, uploads, mail and CRM sync. Compare page addresses and important records. Deploy with a rollback plan and protect orders created during the change.
When to get help
If an update causes blank pages, errors or lost features, restore a working version first. At banano.ru, WordPress and similar CMS updates start at RUB 9,000; complex cases are quoted after diagnosis.
