问题
I inserted a few Vertices and Edges in a new graph. I've saved the resulting grapSON in a json file. Then I tried to import that json file into a new graph with the Migration tool. It only partially worked. I had a new graph with my Vertices but they had no properties or Edges like that:
{
"id": "c39f435b-350e-4d08-a7b6-dfcadbe4e9c5",
"label": "user",
"type": "vertex",
"_isFixedPosition": true,
"_isRoot": true
}
Does anyone knows how to "trick" the migration tool to create new graphs? I'm trying to migrate an existing SQL DB to a graph so I could generate the graphSON programatically.
回答1:
A way I just worked out is to use the Data Migration Tool to export the current graph database (connect as a Documents DB) as a JSON file. Then on the portal import the exported JSON.
Added the graph with vertices and edges in tact.
