Our vB4 (+vBSEO) installation sits in /forum/ and I wish to upgrade to XF 1.1. My options are as follows - Install XF in /community (or other folder) and then perform migration. Keep the /forum/ folder for XF installation. Question #1: I'm not sure how'd the process be if I wish to keep the 'Forum' folder intact. Is that possible, if yes, how do I install XF in existing /forum/ folder? Question #2: How long will I have to keep the vBulletin files on the server? Question #3: vB 3 importer has support for profile fields. Can I use it to import existing vb4 installation and then use Paul M's importer to import the attachments? Has anyone tried this? Question #4: Sitemap Generator: Does it really make a difference? Or would you recommend that I setup higher frequency of crawling in Webmasters account? Question #5: What are the areas I should pay attention to so that I do not repeat mistakes done by other admins during the migration? (Specially related to database settings, server settings etc.?) I many have further questions Thank you in advance!
