Transfer accounts between servers with Ispmanager: Import-user
We have to transfer some accounts (imagine that we have to transfer ACCOUNTM from SERVERA to SERVERB).
We don't want to loose any email, any log of webstats, any database update so... what is the better way to do it? We would like to convert that thread in a how to transfer acounts. 1) 48 hours before transfer the account Reduce TTL (Time To Live) of the ACCOUNTM at SERVERA vi /etc/namedb/zones/ACCOUNTM Change "$TTL 3600" to "$TTL 300" Restart namebd ("rndc reload") 2) Go to destination server (SERVERB) and fill the Import User fields. After the "ImportUser" is done from the remote, at SERVERB set for that user/site: * IP on the new server * DNS servers on the new server 3) Go to SERVERA and modify main IP for the site/user transfered to the new IP Questions about that process: Could be sure with that method that no email will be left on old server (SERVERA)? Feel free to complete/modify/improve our howto. -------------------------------------------------------------------------------- Some more comments about "Import User" feature: https://SERVER/manager/ispmgr?func=h...=backup.import "Location - you can choose the location of user's data backup (Use Backup option to create a backup)" -> does that option exists? There is a little translation mistake here (english version): https://SERVER/manager/ispmgr?func=h...=backup.import "Пароль - access assword to the control panel on the remote server." would be "Password - access password to the control panel on the remote server." "Passwords from SASL-bases will not be moved. So, you will probably have to change your mailbox users' passwords via the control panel." I think that now it works with SASL passwords ;) Feature that we talk some months ago will be really useful: http://forum.ispsystem.com/en/showthread.php?t=208 -------------------------------------------------------------------------------- Have a nice day. |

More on Import-User with Ispmanager
Quote:
We want all emails/data on database beeing updated to new server SERVERB. If not, how could we really have updated emails/databases? Some ideas to solve/improve that issue (does they work?): 1) Set DNS entries on SERVERA of that user to SERVERB before doing the "Import-User" Posible problem: if an email is received while ImportUser is beeing done, then email will be returned (failed). 2) After the "Import-User" at SERVERB, then set dns entries on SERVERA to SERVERB, and execute again the "Import-User", in order to receive again the data from SERVERA while transfer is beeing done. Posible problem: Does the second "Import-User" delete all data recevied at SERVERB? So if any email has been received at SERVERB it will be deleted!!! Any idea or way to do it better? Thank you. |
User Import does not delete anything. It makes a user copy on another server.

We really hope that the howto was made by Ispmanager developers, so we can discuss about that and all users and clients see the benefits of that soft. I thing that it could benefit Ispsystem and all their clients. |
Any update on that topic?
Any Ispmanager developer or techinican that could add more light on that feature? Thank you. |
if i got it right you want more detailed description of ISPmanager modules and backup particularly. so i can assure you that we have the screencasts coming in for the next releases.
