Transfer userman to difrent hardware

Well I was tryin to transfer userman database from my x86 system to routerboard 450.
I was try to have same setup so I named interfaces same and give him same IP addresses …(not exactly) and when I try to load my userman with command (/tool user-manager database load
) I have this error:Failed to load user-manager database backup
action timed out - try again, if error continues contact MikroTik support and send a supout file (13)
Probably this is because litle difrences betwen difrent IP and hardvare (maybe MAC adresses) …
Is there any way to transfer userman database on difrent hardware ?

User manager database load can take some time. Console waits 30 seconds, then displays this timeout message. It does not actually mean, that backup/restore was unsuccessful. Try /tool user-manager database print after a few minutes to see the result. If there was an error, an error message will be displayed here. Otherwise the loading of a backup was successful.

When I try to load I still have this mesage :

Loading user-manager database backup
Failed to load user-manager database backup
action timed out - try again, if error continues contact MikroTik support and send a s
upout file (13)

Then /tool user-manager database print I see this error:

size: 47 kB
in-use: 100 %
error: “write error: No space left on device”

I use routerboard 450 with only 64 Mb so I look size /store disk print

Flags: S - system

NAME TOTAL-SPACE FREE-SPACE STATUS

0 S system 61440KiB 17812KiB ready

My database is only 9 mb so there is enough free space … I have no idea what is wrong …
I was manualy make configuration (with .rsc files) so that my routerboard configuration looks same like on x86 router (with few changes) and everything is work OK (usermanager with hotspot and pppoe server) …

I have the same Problem, it is very strange .I use an other Browser and everything is okay!

To create a backup, you need at least twice as much space as database size. You can try deleting some logs. But be aware of “log deletion issue”, see my post Wed Aug 19, 2009 2:53 pm here: http://forum.mikrotik.com/t/v4-0rc4-where-do-users-check-there-usage-now-error/30723/12 .

If you want to delete some logs, you either have to wait until the next release of RouterOS v3, or delete some logs and clear undo history in console:

/tool user-manager history remove [f]

You could also try to run “rebuild” command before backup - it usually reduces database size. How many % do you see under /tool user-manager database “in-use”? If, for example, in-use=70% size=10MB, this means, that after rebuild database size will be approximately 7MB. But again - to perform rebuild, additional disk space is needed.

Thanks!
Also can you give me some sample command which I can use for deleting logs ?
With browser it was very slow …

The particular line is not possible to add to scripts, but anyway from console to delete from 20 to 135 log entry, you have to use the command,

/tool user-manager log print without-paging
/tool user-manager log [Enter]
:for i from=20 to=135 do={ remove $i}
