upgrade Confluence Server from 3.5.13 to 6.9.1

[文铮 王]

Version of conflunce that the company is currently using is 3.5.13

I have recently installed version 6.9.1 of conflunce and are ready to use。

Can I import the old version of the data content into the new platform?

or

There are other ways to upgrade？

Nope. It is not the right thing to do.

It has always been advised to use data imports for same version of Confluence or JIRA .

It may work - but the problems that could come with it could be serious and without any proper explanation.

I would advise you to upgrade Confluence with the data in it instead of using just data of one version of confluence to another.

But remember , do not directly upgrade from 3.5 to 6.9  - the gap there is huge. Try going to a versions between 3.5 and 6.9 first .

HI @文铮 王 

Welcome to the community!

As you are using too old confluence and the latest confluence version is 7.x.

In between this ..there are lot of major changes that have been released.

So it's better to go through all the confluence release notes, upgrade matrix and supported platforms and then decide.
