Migration of Old Database (FT 8.2) to New Database(LTS 2016)- means with existing old data to be migrate in new database

[Avi_Jain]

My old version of nuxeo was FT 8.2. Now, I have Upgraded to Nuxeo8.10 LTS 2016. I want my old data from old database into new nuxeo database. Is there are any steps by which we can easily migrate database with old data. Can you please share what you did to resolve the issue ? Thank you for your Support.

Hi Avi,

What do you mean by old versus new database ? Did you change your DB ? For instance MySQL -> MariaDB ?

Did you have a look at https://doc.nuxeo.com/nxdoc/upgrading-the-nuxeo-platform/ ?

[Avi_Jain]

No not from mysql to Maria DB. It means from version 8.2 database to 8.10 database.. Whenever we upgrade nuxeo, every version has new database.

[Kevin_Leturc]

Which DB do you use with Nuxeo ?

[Avi_Jain]

I am using mysql database.

No i don't want to upgrade mysql version. I just want my old records of nuxeo 8.2 into nuxeo 8.10 database.

[Kevin_Leturc]

Ok, this is not related to nuxeo then. You want to make a copy of your database nuxeo to another database in the same MySQL.

I tried same u told me i.e. When I connected with old database with new nuxeo server, it was not worked. It gave me nullpointer exception.
