No, I did not migrate data after setting AdvancedFileSystemStore.<br />Also, I am having the same issue with a previous 6.2 &gt; 7.2 upgrade (unable to export).  Below is the log file. I will execute the data migration using AdvancedFileSystemStore option to see if that will resolve this new error.<br /><br />Error: An unexpected error occurred with publication process.

Did you migrate the old store after setting the AdvancedFileSystemStore?<br />You need to do that in Server Administration -&gt; Data Migration.<br />Btw. If you have no real need for some reason, the standard store is just fine. If I remember correctly (please correct me if I am wrong here), the advanced store just places the files in more folders. This was done due to several old filesystem limitations (e.g. FAT32 only supported 65535 files per folder, some filesystems (ext2) had huge performance problems with large numbers of files, ...). If you use ext4 or NTFS, it shouldn&#39;t make a difference anymore and I would stay with the default.

I was able to export after commenting out dl.store.impl=com.liferay.portal.store.file.system.AdvancedFileSystemStore <br />It is now dl.store.impl=com.liferay.portal.store.file.system.FileSystemStore

What value did you set to &#39;dl.store.impl&#39; property in portal-ext.properties?

Jorge Diaz 2020-02-24T20:16:50Z BRODY HIGGS JR https://liferay.dev/c/message_boards/find_message?p_l_id=119785294&messageId=118580151 2020-02-24T19:48:32Z 2020-02-24T19:48:32Z

I did not change system settings, but I did set the &#39;dl.store.impl&#39; property in portal-ext.properties file.  This is a new install of Liferay not an upgrade.

BRODY HIGGS JR 2020-02-24T19:48:32Z Christoph Rabel https://liferay.dev/c/message_boards/find_message?p_l_id=119785294&messageId=118579763 2020-02-24T18:25:17Z 2020-02-24T18:25:17Z

Ok, the startup error looks unrelated, but I might be wrong here.<br />Did you set the dl.store.impl? It seems, something is wrong with it. Did you per chance change something in System Settings -&gt; File Storage? Did you change something else that might be related?

It seems to be related to the document library. Do you have any special settings there? Did you set dl.store.impl by chance? Are there any exceptions at startup that might be related to that (e.g. modules that cannot be started)<br />Which version do you use exactly? CE, EE, patch level?

Can you check the logfile? There has to be some exception there that points to the root cause of the issue.
