Hi, I am about to deploy my first Rails app, but am a little worried about certain syntax changes from Rails 1.8 to 2.1(which I will be using). I’m finding it hard to get my head around what happens if the web hosting company upgrades the Rails version…this will obviously cause my app to completely and utterly die. Is there a way to get around this or would I have to purchase a dedicated server so I know exactly which Rails version I am developing for. Thanks for any help. I’ve only been using Rails for two weeks. Best, C ---

Not necessarily. I’ve been able to deploy apps written in Rails 1.2 on a server running 2.1 with no issues. Most of the issues that are likely to come up are pretty well documented.

This is what freezing is for. If you freeze your version of Rails as part of your deployment, you can be guaranteed what version of Rails your app will be running with since the full stack will be included as part of your application. – Alex ---

Thanks Alex for taking the time to explain all that. I will be looking into freezing shortly after your heads up. ---

You should never depend on a shared server gems, basically you are not in control and a sudden change in them could brake you application. Try to kee as part of your app any library or gem that you rely on to avoid this problems. – Aníbal Rojas > **[Home - Has Many Developers](https://hasmanydevelopers.com/)** > > We are the best choice for your building design and development > **[RUBYCORNER.COM](https://www.rubycorner.com/)** > > RUBYCORNER.COM - Contact us for any business inquiries [http://anibal.rojas.com.ve](http://anibal.rojas.com.ve) On Jul 25, 2:09 pm, Clinton Beattie \ **Author:** ![messismore](https://www.ruby-forum.com/letter_avatar_proxy/v4/letter/m/54ee81/32.png) [@messismore](https://www.ruby-forum.com/u/messismore)\ **Post date:** [July 26, 2008, 1:44pm UTC](https://www.ruby-forum.com/t/st-deployment-rails-version-problems/143979/5 "2008-07-26T13:44:47Z") Thanks.
