Hi @Swati123, if you're trying to call the API to create the visualizations and dashboard, I believe you just need to add ?overwrite=true to the query to avoid getting 409 errors.
If you're trying to use the import UI, the file to import has a different format than what the saved object APIs returns. The attributes of each object in the array are prefixed with an underscore and are named differently (ex: _source instead of attributes, etc).
Import file example for a single visualization:
[
{
"_id": "saved_object_connected_to_saved_search",
"_type": "visualization",
"_source": {
"title": "saved object connected to saved search",
"visState": "{\"title\":\"PHP Viz\",\"type\":\"horizontal_bar\",\"params\":{\"type\":\"histogram\",\"grid\":{\"categoryLines\":false,\"style\":{\"color\":\"#eee\"}},\"categoryAxes\":[{\"id\":\"CategoryAxis-1\",\"type\":\"category\",\"position\":\"left\",\"show\":true,\"style\":{},\"scale\":{\"type\":\"linear\"},\"labels\":{\"show\":true,\"rotate\":0,\"filter\":false,\"truncate\":200},\"title\":{}}],\"valueAxes\":[{\"id\":\"ValueAxis-1\",\"name\":\"LeftAxis-1\",\"type\":\"value\",\"position\":\"bottom\",\"show\":true,\"style\":{},\"scale\":{\"type\":\"linear\",\"mode\":\"normal\"},\"labels\":{\"show\":true,\"rotate\":75,\"filter\":true,\"truncate\":100},\"title\":{\"text\":\"Count\"}}],\"seriesParams\":[{\"show\":true,\"type\":\"histogram\",\"mode\":\"normal\",\"data\":{\"label\":\"Count\",\"id\":\"1\"},\"valueAxis\":\"ValueAxis-1\",\"drawLinesBetweenPoints\":true,\"showCircles\":true}],\"addTooltip\":true,\"addLegend\":true,\"legendPosition\":\"right\",\"times\":[],\"addTimeMarker\":false},\"aggs\":[{\"id\":\"1\",\"enabled\":true,\"type\":\"count\",\"schema\":\"metric\",\"params\":{}}]}",
