I want to update from DNN 4.4.1 to 4.8.1 on my hosted DNN site before undertaking new development on my site. 

This is the firs time I've planned a DNN update.   I understand the procedures for updating DNN itself but I do not understand how to 'update' or prevent overwriting the few 3rd party modules I've installed.  

Do I simply unzip / overwrite the entire DNN install then reinstall the 3rd party modules? 

What is the procedure or perhaps a pointer to a tutorial on how to do this?

Thanks,

Ken

Ken,

Backup everything first. There are some changes between these versions for child portals - if you use child portals then you can have some problems with unexpected logoff when 3rd party modules within child portal access to portal with regular user permission in background (this is my experience - some modules work with earlier versions only).

Kind regards,

Primoz

Remember you're going to have to modify your web.config file as well

Here's a blog post I made on upgrading a while back
