Well, I don't honestly know, but GD keeps telling me that we have to "optimize our script" for wordpress and yet they OFFER WordPress as one of their freebie software packages.
I think GD is full of crap. So yeah, I decided that switching hosts was my best option.
If you switch hosts though, do your research. I have found that Host Gator is highly thought of and highly rated by every host rating survey I have found. Once I switched, I found their 24 hour live chat tech support to be very helpful as well as fast. Their CPANEL, once you get use to is, is great. It is the equivalent of Host Manager Control Panel.
The database management is a bit different from GD in that Host Gator names their DB files uniquely. This means that you will have to back up all your GD databses and then import their content to your new databases at Host Gator. That is not hard to do, but because Host Gator names the databases a bit differently from what you are use to at GD, you will need to adjust your new wp-config file to reflect changes in DB User, DB Name, DB Password etc.
Also, if you switch, make sure you keep your GD account active until you are absolutely certain your new site at Host Gator (or whatever service you choose) is working.
Host Gator will also do a migrate of your entire root directory for free, but they warn (and correctly so) that some files might get left behind during the transfer process. So, once a transfer is done, you will want to check your newly relocated image/content folders for all your image files, plugins and related images, themes and related images, uploads folders etc.
To help with this, what I chose to do was back up my entire WordPress directory onto my local machine as well as keeping my GD web site active.
Once the transfer is complete (about 24 hours), I changed my GD name servers to Host Gator name servers, pointing my domain to Host Gator servers. That way, I could test my new site at Host Gator servers. Once I figured out what needed to be tweaked, I switched BACK to GD name servers so that my old site would have as little downtime as possible.
I am now doing some tweaking of the new site, using an FTP program to upload any and all straggler files, updating wp from 2.07 to 2.09 etc. Once all that is done, I will change the nameservers once more to point to Host Gator. Hopefully by thien it will all work smoothly.
If you have any trouble, come back to this thread and post your questions.
