SharePoint 2010 Upgrade

Hi.
While doing a Upgrade from SharePoint 2007 to SharePoint 2010 a few issues i came across.

Issue1:
When i did the backup of the 2007 environment it was in a read-only state ... i then proceeded to restore this DB to the new server and then upgrade the DB.  all went along fine until i wanted to do the Visual Upgrade and the options were grayed out?
Solution: i went back to the 2007 environment and switched it off read-only mode did the backup and restored that backup ..and PRESTO ..the options were there ....

Issue2:
I had a lot of health issues with regard to the clean install.  you can either go and disable the rules like this  or you can work thru each one.  most of then had a "Fix Automatically" which you should do and SharePoint tries to resolve it.

Issue3: the farm account needed "Replicated Directory Changes Permissions" in AD.  Solution: just give it permissions by following the article.

Issue 4: when a people search was done the url that it linked too ould not resolve ...
when i had setup mySite i provided it with a path that it should use but ALAS!!! ...it doesnt do this. Solution: you would need to run crawl on the content sources and make sure the crawl account used has access to the Service "User Profile Service Application".

Issue 5: when completing the final step and moving users into the SharePoint ... please make sure that the users exist in the new Domain .....
so now i have a sucessful Upgrade from SharePoint 2007 to SharePoint 2010  complete with MySites and public profiles .......DONE!!!!!!!!!1

Just a side note ...the hardest part was getting the User Profile Synchronization job to work.
a very exciting project which i really enjoyed ...

Till the next issue/problem
