you will need to speak with your host to know which is your ssl directory, mine is httpsdocs/ instead of httpdocs/
you would then either copy all your site files from your current directory to the ssl one (like httpsdocs) which long winded imo
or better still see if your hosting provider gives you the option within your hosting settings to use a single directory for SSL and non-SSL
our site is www.futurewristic.co.uk and we had some issues after going to https.
the product galleries stopped working and the fix can be found here
you may or maynot find the navigation links "next" and "last" on the search results page are broken.
Hope this helps?
