is there way to backup thread and forums only and install new Mybb and restore it
When I planned a migration from 1.6.8 to 1.8.9, I created a new install of 1.8.9 fresh out of the box and preserved that database. When I performed the upgrade from 1.6.8 to 1.8.9, I saved the entire database then hooked it up to the clean install of 1.8.9. The reason I did that is because there were old plugins and questionable templates plus other problems relating to the smilies, default graphics and themes and templates. There were a few customizations in 1.6 that were not compatible with 1.8.
So I replaced several tables in the converted database with ones from the clean install in order to make the changes I wanted to maintain. I dropped the converted attachtypes, icons, settings, smilies, settinggroups, signup_questions, templatesets, templates, themes, themestylesheets, and imported new from clean install.
By creating a new theme based on the new Default, I manually entered css styling and modified templates to re-create the look and feel of the old theme. Once done, put it online.
By doing that process, which was done on a local test server, I was able to plan the sequence of migration events in advance of making them on the live forum, so there was maybe only one hour of downtime total, and most members didn't see it because it was made at 4:00 a.m.
This method made it possible to see where the customization done by previous owner were, and to decide whether to drop them or recreate them. Maybe someone more experienced than I would choose a different method, but by doing it the hard way, I got a much better feel for the workings of the innards. Not bad for someone who never saw the ACP until 7 months ago.
Migration from 1.6 is much more difficult than from 1.8.8, but my forum members agree it was worth it. Looking at the requests for help in this forum, I'd say it's almost a certainty a theme is causing the problem.
