[Gerald Okeke]

Greetings,

I seek assistance on how to migrate Dspace and database from Dspace 5.2 installed on WINDOWS 7 computer to fresh installation of Dspace 6.3 installed on Ubuntu Server 18.04. I have tried copying the Assetstore folder from the windows 7 to the Ubuntu server. But that did not work. I will appreciate help from anyone. Thank you!!

Best Regards,

Hello Gerald,

54321 is your handle prefix, not a valid handle in itself.
Each community, collection and item will be assigned an individual
handle, which consist of prefix/[NUMBER] automatically.
In AIP you can specify 54321/0 in order to export the entire site, see
https://wiki.lyrasis.org/display/DSDOC6x/AIP+Backup+and+Restore#AIPBackupandRestore-ExportingEntireSite

Hope this helps

Thank you Claudia,

I tried using 54321/0 as handle prefix for the sitewide backup, but I still got the same error message. 

Please I would like to ask how I can get the specific prefix/[NUMBER] for the several communities I have on Dspace. I would like to learn how to backup and restore either as a community, collection or item.

I have also attached a screen shot of the exception I got when tried doing the sitewide backup. Since the exceptions still reads "Cannot resolve handle "54321" could there be a way to specifically confirm the handle no of the dspace by running a command?

Thank you,

Best Regards,

Okeke Gerald

Hello Gerald,

you wrote earlier, that you ran update handle prefix script.
This will update handle values in the database.

Did you change the value in your configuration file as well?

Hope this helps

I actually changed the Handle number back to the default "123456789" value. And then the backup was successful. I am trying to do a restore now. If I have any challenges I will get back to you. Thank you.

Dear Claudia,

Kindly find below the picture of the exception I got while doing the backup. Apparently it looks like some data ( communities/collections/items) were backed up. But the backup was not complete. I have attached a screenshot of the exception I got at the end of the backup process. Kindly assist me in addressing this issue. I tried doing a restore. But after some time I got another exception. Though some data were restored. But when I checked the Dspace site. I did not notice any change in Dspace Site. The few items restored did not show on the website.

Below is the screenshot of the data that was backup.  About 6gb of data.
