+ ethereum account update <address>
+
+Update an existing account.
+
+The account is saved in the newest version in encrypted format, you are prompted
+for a passphrase to unlock the account and another to save the updated file.
+
+This same command can therefore be used to migrate an account of a deprecated
+format to the newest format or change the password for an account.
+
+For non-interactive use the passphrase can be specified with the --password flag:
+
+ ethereum --password <passwordfile> account new
+
+Since only one password can be given, only format update can be performed,
+changing your password is only possible interactively.
+
+Note that account update has the a side effect that the order of your accounts
+changes.
