Apache Friends Support Forum

Poking around the FAQs and the forum here, I haven't seen this addressed at all, so I thought I would ask. If I've installed an older version of XAMPP, used it and placed working data into MySQL, how do I think upgrade to the next version of XAMPP safely?

I use a Windows computer (NT on one and XP on another). I installed XAMPP using the installer programs. I'm sure I'm just being naive and ignorant here, but what do I do when I upgrade:

1) Just download and install the latest XAMPP package. Everything will then be fine.

2) Don't ever download and install XAMPP again. If you want to upgrade Apache, download and install it safely. MySQL, PHP, etc. -- same thing.

3) Export your data from MySQL (backup?), backup htdocs folder. Uninstall XAMPP. Download/install latest XAMPP. Import data that was backed up before.

4) Some other process entirely that I'm not even thinking of.

Thanks in advance.

I haven't done an XAMPP upgrade yet. I'm still using 1.4.9, since it most closely matches the versions on my web server accounts.

But I would probably use method #3, and instead of backing up only the MySQL data and the htdocs directory, I would backup the entire XAMPP directory first, and afterwards use a file comparision tool (I use BeyondCompare) to merge my changes back in.

The MySQL databases should be backed up as .sql files, instead of, or in addition to, backing up the raw data files, since if you're upgrading MySQL, the old and new versions might not be binary-compatible. The mysqldump shell command or phpMyAdmin's export function can be used for this.

1. Backup the known directories in htdocs (because some parts of it get updated with a newer xampp).
2. Backup "\mysql\data\" directory.
3. Now just remove/uninstall the xampp folders completely.
4. Do a clean install of the new version, and restore back what you had taken in steps 1&2.
This way, no slowing, conflicts, lost features, etc.

And that is how I do it.

That's what I did, and it worked!

Thanks for the advice.

Or you can download and install the upgrade-package...

I *HAVE* tried the upgrade package. There's lot of potential problems there.
