Where can I find instructions on how to upgrade an old vcash wallet (from like fall/winter) to the new one?
first backup the old wallet.dat!
extract/install v0.6.0.3 (rename/overwrite the old Vcash.exe or recompile)
there are two ways to upgrade and/or import the old wallet
1. edit the config.dat
change "deterministic": "1" to "deterministic": "0"
keep/copy the old wallet.dat
2. import private key of your old wallet
make sure you have the private key of your old wallet
rename wallet.dat and start vcash to create a new wallet.dat
use console/rpc command importprivkey
