Drupal Database Migration

I need a small database copied from an existing Drupal website to another. The data to be copied includes Blog posts and content, images, basic page,s. The destination site has some existing content, but not much. The task involves adding the new posts and content to the existing data without deleting anything.

Ideal Skills and Experience:
- Proficient in Drupal
- Experience with database migration
- Familiarity with content management systems
- Attention to detail to ensure no data is lost or deleted.

thanks
