I am running OS X 10.4 on my MacBook Pro and want to upgrade to OS X 10.6.2 or later. How can I do this?

Snow Leopard (OS 10.6) requires an Intel processor and at least 1GB of memory. (Note: the installer will not work on PowerPC Macs, or on most recent Macs introduced after Lion (OS 10.7) was released.).
The MacBookPro has an Intel processor so if you have at least 1GB of memory (2GB or more is better) you are good to go.
Purchase the Snow Leopard Disk. Then proceed with installation.
You could upgrade directly over OS 10.4, but I would recommend doing the following.
1) Using Disk Utility from the Snow Leopard disk, create a new partition formatted as Mac OS Extended (Journalled). (Alternatively, use an external drive and use Disk Utility to RESTORE your OS 10.4 partition to the external drive. This is a clone. Make sure you can start up from the external drive after the restore. Then format your internal partition to Mac OS Extended (Journalled).) [Note: to get to Disk Utility on the Snow Leopard disk, open the installer (if not already open), click on Utilities and Restart. Disk Utilities is under the Utilities menu after restart.]
2) Install Snow Leopard on the blank formatted partition. During install, the installer will search your Mac for any partitions with an OS on it, and then ask if you want to import OS settings, apps and/or files. Do the import to move your OS settings, apps and files to the Snow Leopard partition. If you decide to not import, you will have a "clean install" of Snow Leopard instead.
3) After installation and startup in Snow Leopard, go to Apple menu and do Software Update. This will bring you up to OS 10.6.8.
You will now have a dual boot Mac and can start up from either OS 10.4 or OS 10.6. When I upgraded from OS 10.4.11 to OS 10.6, some of my printer and scanner drivers did not work in OS 10.6 until I could find suitable drivers. In the meantime, I could still start up from OS 10.4 to print or scan.
