What To Remember When Swapping Operating Systems
Maybe you’re fed-up with the Windows world, and have finally decided to ditch Microsoft for a nice Red Hat and some YUM support. Or maybe you’re doing the opposite, and have decided to forsake the world of Linux, and instead pick up something a little more stable and with better tech-support. No matter the reason, swapping entire operating systems can be quite a hassle, and there are a few things you should keep in mind when making the big move.
For starters, there’s not much incentive to make a swap while your server is still up and running. If your hardware is at the peak of its performance, and everything is grooving along with your current OS, there’s just not much need to perform such a drastic measure as changing whole operating systems. The occasional OS update is one thing, but to drop anchor elsewhere is a big pain.
That being said, if perhaps your server is at the end of its lifespan, and you’d like to port everything to a new replacement, then maybe changing your OS is a viable plan. If that’s the case, then use the following guidelines to make the transition as smoothly as possible:
1. Not All Cookies Bake The Same: That’s a terrible metaphor, and we know it. Either way, it’s worth noting that not all of your code will be compatible with the new system. For example, Static HTML and Javascript will work just about anywhere, but your new OS may use PHP 5 instead of PHP 4. You may need to learn a whole new coding environment to match the new software, too.
2. Save Your Stuff First: Just because your FreeBSD installation handled your database server fine does not mean a new operating system will play fair with your MySQL. Before making any kind of drastic changes, be sure you have your entire database saved elsewhere, and can get to it later in case of an emergency.
3. Budget Like You Need The Money: Before, during, and after making the change to a new operating system, be sure to keep a close eye on any loose charges that may accumulate. Linux is usually free, but if you’re playing for tech-support, or perhaps help with the installation, be sure to keep track of it. Always know how much you’re spending, as well as where that cash is going.
