Upgrade path from 1.256

[jptechnical]

I have a client with a stock OSC install, the application_top.php file says:

Id: application_top.php,v 1.256 2002/11/23 02:29:39 thomasamoulton Exp $

I am assuming that it is 1.256. I haven't been doing much with OSC for a couple years, I haven't moved on to something else, I have been focusing more on simple CMS sites. So I am feeling a little out of my element and need a little help getting up to speed.

 

I have been through the forum and have tried to piece together an upgrade path but thought I would throw this out for help.

 

I would appreciate any assistance on steps to upgrading this cart to current.

 

Thanks.
