Migrated Web parts from SP13 to SPOnline don't include the chrome type attribute as it is and set to "Default".
So, if I have a web part that its Chrome type is set to "None", it's set online as "Default" instead.

HI,

I have been testing migration tool and experienced extremely slow speed, even for a list of 100 items, it takes couple of hours to even initiate the migration.

1 - Is there anything we can do to increase the speed
2 - when using a csv file, connection is made for every source and destination url. Can we authenticate once and it can used for all the source sites and destination sites.

Prompt for a user and password of the user who will run the service.

Please write a post explaining the need to select the option for Migrating a OneNote as one file, versus a document library with many folders.

We set up Hybrid Search (CloudSSA) so that we can point users to our Modern Search Center (sharepoint online) while we run in hybrid for next few years. But document preview does not work for on-prem files. Per Microsoft engineer, this is being worked on.

Reason : Modern Search uses different preview or microblog service which does not have the ability. Classic search from Enterprise search center has the preview ability

In large IT organizations, especially organizations that already use Office 365 applications, often the O365 global admin is a different team or admin than the SharePoint Online team or admin. The SharePoint Online admin team who would have the SharePoint Online service administrator role, but not necessary the entire O365 tenant global admin role, should be able to run the SharePoint Online Hybrid picker as well as the O365 global admin.

The current 2.1 release of the SharePoint Migration Tool balloons to occupy a huge amount of memory and disk space when scanning millions of files. I find this unnecessary for a program that is essentially creating a catalog of files.

After scanning 15 million files, memory usage is at 12 GB and the list.dat file is 45 GB.

Don't immediately begin migration of files upon resuming a scan only session. I had a scan only session running for 175 shares that crashed the SPMT. Upon restarting and resuming the migration, the tool began actually migrating the files when I only wanted to scan them.

SharePoint Migration tool does not migration Full permission from File share to "Full Control" permission level in SharePoint Online. The mapping of Full permission to contribute is not a correct scenario because it does not provide Share folder permissions. This is a serious flaw. We hope there is a workaround or fix very soon.

Pause/resume feature of SharePoint Migration Tool is disabled.

Offer option for top navigation links to open in new tab by default.

"Copy path" making it possible to copy the path to a point in the file structure would help the organisation to learn "what to find where" by pointing at exact not-manually-entered locations.

It would decrease the tendency of the structure to become a "write-only-memory" with increasing size and time.

The PowerShell cmdlets for copying Taxonomy Groups and Content Types (Copy-SPTaxonomyGroups, Copy-SPContentTypes) only support passing credentials in a legacy method, this blocks copying these items to SPO if you have conditional access (or have disabled legacy auth) enforced for your tenant.

Increase the number of keywords that can be followed on SharePoint without crashing the search system.

One of the base requirements for the migration tool is 150G of available space or an SSD. Many of the organizations we support have relatively small C drives though plenty of storage on other attached storage. The migration tool seems to error out if the C drive has < 150G of available space. Please allow the admin performing the migration to specify where the migration tool can obtain it required space.
