About upgrading magento 1.8?

Question

I'm currently using Magento CE 1.7 for my shop and I would like to upgrade to Magento CE 1.8.

I would like to know if I can run to issues upgrading with the 3th party extensions I'm using and any core code modifications I've made. In short I'd like to know what I can expect when I upgrade the installation.

Any tips or help would be appreciated.

short answer: yes

long answer: it completely depends on what extensions you are using, the modifications you've made to templates or code. If you've overwritten core files (Moving a file to app/code/local/Mage/... and modifying the code) etc etc.

Best approach in your case would be to make a copy of the store locally, do the upgrade and see what happens. My guess is there will be a few issues that you can then go about fixing.

Once you have your test environment running perfectly you can either copy it to your live environment or do the modifications you did on test again on live.
