Hmm.. I have been working on this for quite some time and this time it worked. I spend an entire day on this – I faced a lot of problems. I used the script suggested by NoWhereMan at flatpress.org. It didn’t work at first time properly. I totally messed up the first time. But I had backed up the whole blog so it wasn’t an issue. I even had a local WAMP setup running at home where I experimented. All the wordpress posts appeared as draft entries in flatpress and I had to take some time to get everything as it should be..
But I am glad that I finally nailed this..
