I am trying to copy a whole website with all its contents, configurations, settings, etc. to a new domain. The website's Typo3 version at the moment is 4.5.x. Once I've copied it over I want to upgrade the version to 6.2.x.
I know this is quite broad, but I really need some help on this so I can get this done by the end of the year.
Any help? :)
Just copy all files and make dump of whole database to make copy.
DO NOT forget change credentials of the database connection otherwise you may accidentally change data of old domain being at new one.
probably you'll need also change domain specific configs... but that depends on the page.
For updating just check instructions in TYPO3 docs... there's no any singl answer it can be easy just like updating all extensions, all it may be impossible, cause extenasions methods may be depreciated/removed in 6.2...
