i think its just a waste of time.
for you is easier to install new magento 1.7 and import your products and users.
you will get clean working shop,
then you have to modify your theme as well.

do not go through upgrade process.

then if you need, import your orders history and statistics, etc.

It’s possible I suppose if you were to upgrade gradually. (from 1.2.x to 1.3.x to 1.4.x, so on and so forth). Keep in mind what 3rd party modules you have as well as knowing that once you hit 1.4.x there are some template changes to take into account.

If you are not using a lot of (outdated) 3. party extensions or code customizations it should not be that hard. You will first have to upgrade to v1.4, then to 1.7 which uses a new pear updater. The most common issues arise from incomplete database upgrade so make sure no one is accessing the store while the upgrade process is running (block access by IP, chmod or similar). I recommend using ssh/command line for the upgrade process.

And as always, make sure to create backups!

Upgrading Magento is a breeze. The issue is your 3rd party extensions / theme. I would DEFINITELY do it on a test server first. Or even disable all 3rd party extensions, update, and then start with a fresh 1.7 install with the updated DB. Then add the extensions you need.

I did an upgrade from 1.4.0 to 1.4.2 and then to 1.7.0.2 this weekend.

It took me 14 hours in total with a lot of testing. The biggest problems I had were:

- missing tables when running the normal upgrade routines
- incorrect constraints in the database
- template issues with an old template
- 3rd party plugins that needed an update or re-installation

Overal I feel confident in doing it again it took me 2 hours in preparation in a test env. Another 1 hour in upgrading. 2 hours in testing and then doing it again from 1.4.2 to 1.7. After that I need 2 hours to get in back to the live server (a large upload) but in the end it is running like never before.

Client is happy with all the previous bugs gone but I learned 2 things:

- Test, test, test
- run it on a separate environment and upload it to the live environment afterwards

My 2 cents; I would go for 1.7 directly because 1.2 is really old....
