Migrate webcontent from 5.2 to 7

[7年前 に David Bougearel によって更新されました。]

Hello,

Could you help find the best way to be able to migrate existing webcontent lar file from 5.2 to 7.0 ?
As i see, webcontents in 5.2 may content image for images gallery, document library, templates and structures ...

I know liferay 6.2 and 7 so i need to know how to migrate this 5.2 webcontent lar file.
Are they some upgrade tools to do this ? documentation ? Do i have to create migration scripts ?

Thanks a lot for your support.

Best regards,
David.

It is not possible. LARs can only import from the same version of Liferay, they are not coded to support content upgrade during import.

As i see, webcontents in 5.2 may content image for images gallery, document library, templates and structures ...

And those are only the major differences, there's tons of minor differences that prevent this kind of thing.

Your only "automatic" path will be to load the lar into a 5.2 environ and then do incremental upgrades in the environment to work your way up to 7.

It might technically be easier to manually migrate the stuff from 5.2 to 7 by using a lot of copy n paste depending upon the size of the content.

Hi David,

Thanks for your quick answer, i was thinking to the same approch (first migrate by steps, otherwise manually migrate content to L7).
Have a nice day.

Best regards,
David.

Hi,

Is it the same process for EE webcontent data migration ? i mean from 5.2 EE to Liferay DXP ?

Thanks.

Best regards,
David.

Yes, you'd have to incrementally step from 5.2 (EE) through Liferay 7 CE (DXP).

Enterprise customers are not exempted from this necessary data migration path.

Note that for such a jump I would not worry about updating plugins to each incremental level, you're just trying to get your database and data folder upgraded to 7.

Hi David,

Thanks for the confirmation.

I have a question, i've tried to import webcontent lar file inside a 5.2 EE SP5 and while it was importing, it was saying 'An article with ID XXX already exists. New id generated YYYY' on a fresh database. I was wondering why ? (after the transaction commit, no journalArticle had id XXX :/)

And then when i tried to move to 6.0.6, an upgrade database instruction (UpgradeAsset) was failing with a 'duplicate entry'.

Have you an idea of what is going wrong there ?

Thanks a lot.

Best regards,
David.

It's been awhile since I've been in either 5.2 or 6.0, but most of the time import or upgrade failures can point to some data corruption.

I usually want to see what the exceptions are, trace them in the code to see what was going on at the time, and use those details to try to pinpoint the data that might be causing the failure.

DB upgrades are pretty painful, as a normally running Liferay will be fine w/ bad data at the version it is at, but upgrades tend to fail on them.
