Hi all,

I'm using SPMT to migrate my onpremise SPS 2010 to Sharepoint Online, I have more than 10.000 site collections and 300.000 subsites.
The speed migration is very slow, I created a CSV file with 40 document libraries and this tasks end after 10 hours, independently amount of documents.

We have a 60Mb symetric internet connection, LAN 10Gb or 1Gb ethernet, windows 2008r2 sp1 servers, 32GB ram and 8CPU

I allready have all site collections and subsites created in SPO, the SPMT only need to create DocLibs and files.... I'don't understund where is the bottle neck...

any help will be appreciated, thanks!!
Mauricio.

    Hi EchoDu,

    based in my testing, if you have an organizational structure with site collections which has many subsites, doclibs and metadata, so the migration speed will be slow...

    thanks for your help, regards!
    Mauricio.

    Hello @Mauricio Poggio Veiro ,

    Please follow these guidelines to help improve SPMT migration performance.

    1.Improving the migration computer speed

    Suggestions:

    • Install and run the migration tool on a computer with better disk performance, such as a fast SSD.
    • The disk that hosts the migration working folder impacts migration performance. If there are multiple disks on the computer, configure the working folder setting to point to the disk with the best performance.
    • Stop other applications that create a heavy load of disk operations when doing the migration.

    2.UsingJSON or CSV file to do a bulk migration

    If you have many sources to migrate, you can use either a JSON or CSV file to do a bulk migration. To learn more on how to create a JSON or CSV file for data content migration, see How to format your JSON or CSV file for data content migration.

    For more information, please refer to the below articles

    Thanks,
    Echo Du

    there may be several reasons:

    1. Network: do you have any firewalls in use in the current network? You may try to connect to another network and test migration from there
    2. PC: do you have any antiviruses on your PC? try to run migration tool from other PC
    3. Problems wuth user account: try to run migration tool using different user account (less possible)

    Hello EchoDu and sadomovalex, thanks for answer.

    I'm already knows about thats recommendations, network, firewall, harddirve, etc. but I tried from different servers, with and without firewall, more authentication agents, without AV, etc.

    Now I'm trying with Sharegate powershell, and in the same server I could migrate one document library in 6 minutos, but if I try with SPMT the same process takes 40 minutes!! I'dont know what hell SPMT is doing.....

    SPMT could migrate only content? (without checking structure?)

    thanks a lot!
    Mauricio.
    PS: I'm using SPMT with JSON, CSV and standard way
