Upgrade Flash On ASA 5505 Security Plus

I have an ASA 5505 Security Plus. I have a 128mb Flash card that I need to change to a 512mb card. I am confused as to the proper method to do this without messing up my configuration. Can anyone put in simple terms the steps to do this?

Do you have a tftp server to which you can copy data and then to use to boot the Asa from?

What I am worried about is all the files located on the flash drive. Can I just copy the entire disk to another disk via windows?
You can copy the data off using other means, tftp, FTP or using asdm/web interface.

It is best to be prepared I.e. Have tftp server ready/configured to handle anything that might come up.

Here is another reference that could/would help should your windows attempted data transferred flash encounters an issue.
