Skype - moving over histories

I just got the portable skype app that was made available Oct 23, very glad to see this come along as I use a separate computer at the office and at home and very eager to have skype histories and chats all on one. Never used portableapps before but intend to set up their firefox momentarily as I have a new computer and I’m going to put both on the mobile drive.

I have a question: I have all my call and chat history backed up from my old c: drive, can I just paste this over the portableapps Skype Portable and if so, where exactly? The directory where I have the info backed up is:

...AppData/Roaming/Skype/myusername

in that folder there are 4 directories (chatsync, httpfe, IM History, voicemail) and a bunch of other files

I was guessing that the place in Skype portable to paste these was:

...SkypePortable/data/settings/myusername

where I would create the "myusername" folder in the settings folder, then copy in all the files from the original "myusername" folder have backed up from the c: drive?

I would greatly appreciate confirmation

Thanks and very glad to discover your service (wish I'd found this sooner!)
