I'm new in drupal. I have one site that is running on drupal version 7 and now needs to be upgraded. My question is: I have big content in this site, after the upgrade will I loose this content or the content will be saved?

I used to do manual upgrades, but I found that upgrading via Drush is much easier.
drush up updates Drupal core and contrib projects and apply any pending database updates.
drush up --security-only will only install security updates, which I find most useful when maintaining older sites.
