LAR build number 5100 does not match

[Monte Glenn Gardner，修改在15 年前。]

I Installed version 5.2 on my local computer.
I attempted to import a .lar file exported from our current 5.1.2 Liferay. I got the following error:

22:06:52,855 ERROR [ImportPagesAction:85] com.liferay.portal.LayoutImportException: LAR build number 5100 does not match portal build number 5201

You need to change build-number in manifest.xml before importing it on latest version.

manifest.xml can be found when you unzip the LAR file.

I have liferay version 6.1.1 and jboss 7.1.1. After changing the build-number in manifest.xml showed this error:

Just for reference (after all these years without any specific fix to this issue),
this issue is related to your Liferay version installed - and which version of Liferay files are you trying to import.
Check your installed version at
Control Panel >> Server >> Server Administration

Hi,

Liferay stores the build number in the LAR file to check on which version the content was exported. As the export is handling a serialized data of our objects, the data is really tied to the version from where you have exported it. If you try to import the .lar file on another version, Liferay won't let you to import it as the build number won't be the same. You could change it directly in the xml file, but there's a 99% chance that the deserialization would fail.

If you want to migrate data between versions, please use our upgrade processes, currently that's the only way to convert information between versions. Or you could use the API to copy, however it requires some work.

Hello Balogh.. So far i have been able to have 100% success by doing this, though! Unless sometime in the nearest future an error shows and i have the cause reference to this action then.... i have a problem! but so far, so alright! Cheers
