Backup of domain created on Plesk 8.x fails to restore on Plesk 9.x server with the following error:

An error occured during domain update: An error occured during hosting updating: Some fields are empty or contain an improper value.
Do not use quotes, space and national alphabet characters in a password.
The password length should be between 4 and 14 characters long and should not contain the login name.


The problem occurs if user's password of restored domain contains quotes, space and national alphabet characters. It is possible to create accounts with such passwords in Plesk 8.x, but Plesk 9.x policy does not allow to create and use passwords containing these characters. As consequence restoration of domains with users which have incorrect passwords is not possible.


There are two possible solutions for the problem:

1. Reset user's password without using quotes, space and national alphabet characters on Plesk 8.x server, backup the domain again and restore it on Plesk 9.0 server:

2. Change user's password in the backup to meet Plesk 9.x requirements as follows:
     - Change extension of the old backup file to zip;
     - Open it by an archive tool and extract info.xml file;
     - Open info.xml  file in WordPad, find the user and replace his password;
     - Save info.xml file and return it back to the archive file.
     - Change extension of the backup file back to psa;
     - Restore domain on Plesk 9.0 server
