I think that it depends on whether you have a small site or a large site under 1.5.
If small, start with a fresh install of 2.5 and copy and paste your articles across from 1.5, search and download new 2.5 modules/extensions and set up as new.
If you have a large site, stick with 1.5 and make it as secure as is possible. (I have two large sites, one with about 1,000 pages and another with 6,000 pages. I have tried to migrate the 1,000 pages which has about 50 menus and in the end I have given up as there are so many problems with articles/menus/categories etc).
I may decide to build a new site for the one with 1,000 pages but I would expect this to take at least a year if not longer!
this is interesting as my site has thousands of pages and this worries me. what i need to know is,
1. once i have upgraded my site to joomla 2.5 will all of my articles still be there or will i have to then start all over again.
2. you say about making the site as secure as possible, how can we do this
it does annoy me that joomla keeps on upgrading and you keep having to go to the new version. i have had to do this three times now and it is getting beyond a joke.
the last time i done this, i lost over 10,000 pages and had to redirect thousands of them and still i have not done them all as i just gave up.
what i need is, to know that once i have upgraded the site then all the articles are going to be there and i can just have my upgraded template and the articles are still available to show.
basically what i am saying is, once i put the new template up then will the articles show
