It is possible to update Seurat v2 objects to Seurat v3 objects via `UpdateSeuratObject()`.

<p>I have tried to export the monocle data into Seurat and got the error</p>

<pre><code>"Error in Seurat::CreateSeuratObject(raw.data = data, normalization.method = "LogNormalize",  :

<p>Here is my code <code>seurat_SAN_cds_subset &lt;- exportCDS(SAN_cds_subset)</code></p>

I have tried to export the monocle data into Seurat and got the error
"Error in Seurat::CreateSeuratObject(raw.data = data, normalization.method = "LogNormalize",  :
  unused arguments (raw.data = data, normalization.method = "LogNormalize", do.scale = TRUE, do.center = TRUE, is.expr = monocle_cds@lowerDetectionLimit)
Calls: exportCDS
In addition: Warning message:
In if (export_to == "Seurat") { :
  the condition has length > 1 and only the first element will be used"

Here is my code seurat_SAN_cds_subset <- exportCDS(SAN_cds_subset)
Is anyone familiar with this?

There's no default for the `export_to` option, so you just need to specify `export_to="Seurat"`. Note that monocle2 doesn't seem to be compatible with the newest Seurat (3.1) releases.
