The safest and fastest way to move from MoneyWiz 1 to MoneyWiz 2 is via SYNCbits.
If you already have a SYNCbits account in MoneyWiz 1, just log in with it in MoneyWiz 2. If not, we highly recommend that you create one in MoneyWiz 1 and then just log in with it in MoneyWiz 2.
The alternative would be to export your data from MoneyWiz 1 (via Settings/Export) and then import it in MoneyWiz 2 (via Settings/Import). Bare in mind though, that this won’t import anything else besides the transactions. Things like budgets and the accounts themselves, won’t be imported.
