My current blog working on B2 engine is running from 2 locations as I am shifting from a directory based blog to a sub domain based blog. The 2 locations are:
Now that I want to upgrade to WordPress and I have some doubts about the success of the upgrade, I want to upgrade the old version I eventually plan to fade out that is the directory based blog. Now, I want to know that if I upgrade that blog from B2 to WP, will the WP installation make structural changes to the B2 database thus rendering the original blog unusable? If it does nothing of that sort and both the interfaces works all right, I will get some time to test out WP on my blog on the temporary position and later on move the WP to the final place...
