Hi Lynn,
I've just gone through upgrading DNN creative which had a corrupt 3.2.2 version of DotNetNuke and is now running version 4.4 .1
The first thing I must emphasise is to backup absolutely everything, all files and the database.
My first attempt went belly up due to some settings that needed to be applied with my hosting provider.
However, as you are upgrading from DNN version 4 everything should be straightforward.
The same principles apply as in the upgrade video tutorial, make sure you transfer in your web.config file:
- both connection strings
- machine key settings
- date installed
- any other changes you have made, for instance adding the FCK editor
I know that from upgrading version 3.2 .2 I had to remove all compression elements. - So as you say remove page blaster compression for site one.
However, I don't know about the compression in 4.4.0. - if you had not mentioned this I would have just disabled the compression by going into the host menu/settings.
To disable it in the web.config file you will see this section:
< httpmodules >
and
< add name="Compression" >
You can comment out this line by adding at the beginning of the line:
<!--
and adding at the end of the line:
-->
( you will see an example of this in your web.config file for name="Authentication"
The only difference between the install version and the upgrade version is that in the install version it includes the modules within the install folder.
Hope this helps, if you find any more information on compression and upgrading let us know.
I would recommend you test upgrading on a localhost installation first.
Thanks and good luck!
