Update 2nd September 2016
Still WIP but some early feedback
The Export / Import function is excellent
Some things to watch for
DNN <7 although it exports content it does not export files, so images etc need to be done manually (FTP)
DNN >=7 Very impressive, it's 99% perfect points to watch
1. The favicon.ico doesn't export, but this can be helpful as you know your working on the new site as it has the DNN icon
2. If you have added a page stylesheet to a page this doesn't copy either
3. Skins / Containers although the files do copy (CSS, images etc) ASCX files do not and I would advise FTP the whole folder structures
3rd Party Modules
DNN Reports
The SQL queries copy but you may just need to configure the data source
DataSprings - Dynamic Forms (which I absolutely love)
Exports and Imports very well but you need to check
1. If you use a redirect page either in config or question specific they need to set up, I think it uses TAB-ID so unless you have been very lucky with a 1-2-1 match the page defaultsto the new site Home Page
2. If you have any SQL code then when it exports it but with a specific reference to the original database.
Google Analytics
You need to go and enter the tracking code in the Admin function
Skins and Containers
DNN 8 does not use the SolPartMenu so if the original skin references it, then you will have an issue. If your default container (invisible or no-title) does not reference it then all is fine but if other formatting containers do then you may have an issue
Another thing to watch (still testing) the export specifically references skin and containers, that means if the pages of the original site are configured to “not specified” i.e. use site defaults then they are now specifically referenced!
SQL (Still testing)
If your site uses Tables in the database that you have created then (unsurprisingly) these do not migrate in the Export / Import so you need to recreate them from one Database to another. SQL queries are migrated (see Reports / Dynamic forms)
I hope to publish, later, SQL code you can use as an example if you need to reskin when you migrate
