I have a new social networking website that needs to be upgraded from Joomla 1.0 to 1.5. The upgrade will need to be seamless and the site should run perfectly as it did before the upgrade... So this means, upgrading the current components and modules (if they do not run in 1.5) and make sure the DB is running fine... I don't want any loss of data (such as members, content, etc) The person doing this should be an expert with Joomla and have plenty of experience.
Current components installed:
CommunityBuilder (too many plugins here too mention)
Community Builder Advanced Search
Most of these components, also have modules. So the modules will need to work also. I can provide the template for 1.5, it is pretty much the same as the 1.0 template. I'd like as little down time as possible with the upgrade as well... So, I'm looking for a pro that has a lot of experience with this.
