Let me first say I've been with TCH for nearly 3 years and have been a happy customer.
Ok here's my problem. I have a heavily modified IPB 2.0.4 board that I've spent years perfecting. It's a car based board with addons like a garage script, review system, arcade and about 100 mods and features. Anyway, things were great until I just found out my you are switching all your servers to MySQL5 and PHP5. Of course a good portion of my site would be broken. I know if I upgrade to the newest IPB version it would work fine but... I'm not willing to lose all the features and mods (and my 4,500 members aren't either) we now have and many years of work to switch. Also some of the features I added are member supported with $$$ and if those features are broken my site is in trouble.
So am I best off moving to another host that still supports MySQL4 & PHP4 or is there someone that knows what I need to change in the scripts to work with PHP5/MySQL5.. I'm not an expert on this.
Note: I'm begging the upper ups at TCH to consider keeping a server or two with the current configuration.
