How much effort to go from Drupal to vbDrupal?

[VUL Test]

Hi there,

I've been searching around and haven't been able to find an answer to a question I have.

I'm trying to find out approximately how much effort is required to migrate from a current Drupal installation to a vbDrupal implementation. Assume the person doing the job is well versed in Drupal development.

I understand that there are conversion scripts available, but I'm trying to get a feel on about how many man-hours it may take to migrate the style, structure, events calendar, etc.

What are the limitations in the conversion scripts? How far will they get you, how much tweaking of styles, etc will be necessary?

Looking forward to your experiences,

Regards,
Craig

You should be able to use the same styles you were before... although I'm not sure if the conversion script imports data from modules... if they do then it shouldn't take too long at all.

check out the conversion script on a backup. if it works for you, then it wouldn't be a big issue, of course. but if you have issues, then troubleshooting may take some man hours. but i know of no way to estimate that.

most of vbdrupal is as close to core drupal as possible, so in general, most themes, mods, etc. work the same. if you have stuff that impacts logins and sessions, however, those modules may present some problems or require adjustment...

Thanks for the info so far.

Unfortunately I'll not be able to do a test-run on the conversion script for some time yet. I know it's all but impossible for anybody to make an educated guess, but giving me a ball-park WAG of the following will at least tell me if it's worth investing the time to do a proof-of-concept.

Could anybody provide a WAG on the amount of man-hours required to port a Drupal install without any modifications to logins/sessions? Am I looking at a few man-days, tens of man-days, man-months?

I understand the margin of error is high, I guess perhaps if people can provide some of their experiences, I can use that info and guesstimate its applicability.

Thanks very much,
Craig

I honestly couldn't even say that. I'd suppose it depends on how many pages your site has, how many and what modules are installed, what problems you encounter, etc.

I'll see if I can do a test conversion to see what converting is like when I get the chance. It might take a few days though.

you aren't really migrating data to my understanding. the same styles, most of the mods, and the content should not be impacted. login stuff and bootstrap files, for example, are different...most of the drupal in vbdrupal is JUST drupal, however, so i'm not thinking "proof of concept".

i would say if you don't encounter module-specific issues, we're talking hours, not days or months. is there some reason you're not willing to just run the scripts on a backup of your database and see what you get?
