I allways use getresources + importx (Modx extra) to transfer resources to an other website.
Its easy...
Make resource call like this on all resources you want to transfer:
[[!getResources? &parents=`4` &tpl=`exportemplate` &includeTVs=`1` &tvPrefix=`` &depth=`1` &limit=`200` ]]
(use te correct parent, or move the resources you wanted to export to a temp folder...)
The &tpl is like this:
[[+pagetitle]];[[+longtitle]];[[+description]];[[+parent]];[[+template]],[[+alias]];[[+menutitle]];[[+introtext]];[[+content]];[[+templateVar1]];[[+templateVar2]];[[+templateVar3]];[[+templateVar4]];[[+templateVar5]];[[+templateVar6]];[[+templateVar7]];
(use semicolon because importxuses this)
Put the getresource call in a page
Set the page to content type to .txt
Set the template to 'empty'
Visit the page, and copy the text. (A)
Install the Modx extra importX
https://rtfm.modx.com/extras/revo/importx
Put all fields correct in the first line like this: (must match exact)
pagetitle;longtitle;description;parent;template;alias;menutitle;introtext;content;tv14;tv15;tv31;tv32;tv16;tv17; (B)
Paste the text you copied at (A) in the CSV field of imnportX. (first line is the line at B)
Start the import.
Ready....
(notice: modify the settings in ImportX concerning parent, published, etc...)
