I am doing migration from SharePoint 2010 to Office 365. While migrating subsites small number files or small volume size sites are migrated without any issues.
While migrating large number of files in Subsites, then I am getting too large to create index.
Please help on this, how to migrate this type of files using Microsoft SharePoint Migration Tool. If I migrate library wise, then big challenge is permission. Site permissions are not migrating.
Please guide me
