Hi,
I could resolve the slowness issue by purging the events and could upgrade the MangoES to 2.7.10 successfully, but I have got another issue, I cannot see the data sources but can see the data points, do you have any idea?
Cheers

Hi guys,
Thanks for your support. I went for Joel solution and could restore the database on another mangoES 2.5.2 but when I tried to open whatch list or do any thing on Web interface, it's really slow (I could see the watch list), when I tried to open datasources I recived Server error:Timeout, and I couldn't upgrade that to version 2.7.10. I tried several backups for different days but the result was the same. I also tried to boot the mango in SAFE mode but that couldn't help. Appreciate your help.
Cheers

Hi,
I want to extract H2 database from a mangoES version 2.5.2 and restore it into a mangoES version 2.7.10. I tired that, but it didn’t work and the following is the log file output, I just want to know is it possible to do that with different version and how should I do that. I should say that I cannot upgrade the version 2.5.2 to 2.7.10 as it’s a running project and it’s in remote area, I want to restore the database one a mango with version 2.7.10 and send that to site to substitute. Appreciate your help in this regard.

Thanks for the response. According to the following output of the commands, it looks database has got the largest size. I can delete the old backup files to have more size, but appreciate your idea in this regard, and also want to know how to purge the event table.

Thanks,
Mohammad

Thanks for the response. When I am trying to stop/start the Mango I recive the following warnning, I think maybe the upgrading process has not been finished. Is there any way to run it again or do factory reset or something like this to have a fresh one and upgrade it again.Thanks.
