Here’s the situation:</P><UL><LI>The current portal hosts several hosted feature services, some of which include attachments that are as large as total size of 20 GBs.</LI><LI>I’ve tried using AGO Assistant, but it doesn’t transfer the attachments.</LI><LI>I attempted using arcpy, but ran into various errors during the process.</LI><LI>While FME can read the attachments, I haven’t been able to write them successfully to the destination portal.</LI></UL><P>My main goal is to migrate these services, including their attachments, to the new portal without any data loss. Additionally, it’s crucial that the applications dependent on these services in the old portal continue to function without issues after the migration.</P><P>Has anyone faced a similar challenge? What would be the best strategy or tools to handle this migration efficiently and reliably?</P> Tue, 26 Nov 2024 11:04:51 GMT https://community.esri.com/t5/arcgis-enterprise-questions/optimal-strategy-for-migrating-a-data-store/m-p/1562565#M41058 CanDAGDELEN1 2024-11-26T11:04:51Z https://community.esri.com/t5/arcgis-enterprise-questions/optimal-strategy-for-migrating-a-data-store/m-p/1562591#M41061 <P>Hi&nbsp;<a href="https://community.esri.com/t5/user/viewprofilepage/user-id/412384">@CanDAGDELEN1</a>,&nbsp;give the <STRONG>Copy Hosted Feature Services</STRONG> tool in this <A href="https://community.esri.com/t5/arcgis-enterprise-documents/migrate-content-for-arcgis-enterprise-arcgis/ta-p/1365455" target="_self">toolset</A> a shot.</P> Tue, 26 Nov 2024 12:38:09 GMT https://community.esri.com/t5/arcgis-enterprise-questions/optimal-strategy-for-migrating-a-data-store/m-p/1562591#M41061 JakeSkinner 2024-11-26T12:38:09Z https://community.esri.com/t5/arcgis-enterprise-questions/optimal-strategy-for-migrating-a-data-store/m-p/1562597#M41063 <P>Hi&nbsp;<a href="https://community.esri.com/t5/user/viewprofilepage/user-id/10527">@JakeSkinner</a>&nbsp;,<BR /><BR />I tried using the toolbox, but just like with the clone function, I’m encountering the similar error when attempting a file geodatabase export. I’m not sure whether the issue is related to the size of the attachments or a potential corruption in the hosted service itself.</P> Tue, 26 Nov 2024 13:10:34 GMT https://community.esri.com/t5/arcgis-enterprise-questions/optimal-strategy-for-migrating-a-data-store/m-p/1562597#M41063 CanDAGDELEN1 2024-11-26T13:10:34Z https://community.esri.com/t5/arcgis-enterprise-questions/optimal-strategy-for-migrating-a-data-store/m-p/1562604#M41064 <P>Are you able to export the feature service to a File Geodatabase using the item details page?</P> Tue, 26 Nov 2024 13:32:17 GMT https://community.esri.com/t5/arcgis-enterprise-questions/optimal-strategy-for-migrating-a-data-store/m-p/1562604#M41064 JakeSkinner 2024-11-26T13:32:17Z https://community.esri.com/t5/arcgis-enterprise-questions/optimal-strategy-for-migrating-a-data-store/m-p/1562608#M41066 <P>Unfortunately, no, the process also fails there.
