Largest v B forum I have tried this process on was aproximately 38GB size.If you have problems or v Bulletin errors during upgrade, best to check out v Bulletin 4 Installations and Upgrades support forums.Initially, it was designed solely as a rewrite of UBB, in PHP using My SQL, and was meant only for their own forum.Other UBB owners expressed interest in the solution, and they offered to sell it to Infopop, but their proposal was rejected. Tune php and mysql settings specifically for backup, restore and upgrade process.Tune mysql to ensure enough memory is allocated to buffers to speed things up, increase timeout values for mysql to ensure no mysql timeouts and for php.
Added youtube video for steps 1 to 4 outlined above as an example of upgrading from v B 4.2.0 to 4.2.0 PL1.
So I usually don’t compress these backups until after the v Bulletin 3.x to 4.x upgrade process is completed fully. Create new empty database called newdbname and import backup vb3into newdbname Now you should have overwritten all files in /home/username/public_html with new v B version files [box type=”warning”] At this stage, if you are using v BSEO addon and have Max CDN or any other CDN hosted v B php/js/css files served externally, please flush and purge the CDN caches from your Max CDN or CDN provider control panels to ensure you’re upgrading using the uploaded new files and not cached CDN files.[/box] Step 5. Note if you have php opcode caching such as Xcache installed, please disable Xcache from the server and turn off Xcache v Bulletin datastore caching from BEFORE running PHP CLI command line upgrade as it seems Xcache doesn’t support PHP CLI.
Rebuilding Search Index Rebuilding search index can be a time consuming task, so v Bulletin included a way of doing this rebuild via SSH2 telnet via PHP command line.
Creating this video was a bit awkward as for years now, I normally use multiple monitors for different apps and screens so having to condense this video to single monitor recording was a bit of a challenge.
