Confluence Cloud and Attachments (lots of)

[Steve Hastings]

hi all,

I have a client who wants to move across to confluence from sharepoint. They have 60,000 files/attachments comprised of Word, Excel, PowerPoint, PDF, images files. A key criteria will be version control of these attachments. I'm coming across a range of attachment management add-ons in the atlassian marketplace but have yet to find one that would be powerful enough across this number of files (60,000) in terms of version control and view/edit restrictions. Can anyone please recommend an attachment management tool for Confluence Cloud that would handle big file sets and provide version management across a space. 

many, many thanks! Steve
