Updating 1.5.4 Carolina to new version

[eppesen]

Hi guys,
I am wondering about upgrading my web from 1.5.4 "Carolina" to a newer version.
1. What do I gain by updating?
2. How do I do it, and keeping news and all settings in new version ?

1: you'll gain security and prevent problems with a cms that's not compatible with the current php-version
2: read

You'll also see a lot of new features and less bugs. But most important is the security, there are known security leaks in older CMS MS versions, it will be a matter of time before some hacker uses one.

1) create a full backup (database and files) and test it.
2) upgrade to 1.9.3.4
3) upgrade all your modules to the latest version
4) upgrade to 1.10.3
5) upgrade all modules again
