Best approach to upgrade to Jira v7.7 from v6

Question

Our current Jira version is v6 and we have a lot of ticket data.

We are required to move over to a new Server machine and have the latest v7.7 Jira on it.This new machine has no data.

My question is what would be the best approach to upgrade:

1) Install Jira 7.7 on the new machine and then bring in the ticket data from the old v6 server. Is this method possible?

2) Install v6 on new server and then use the upgrade path: v6 -> v6.4 -> v7 -> v7.7 ?

Option 1 will not work.  You must upgrade v6.x -> 6.4 -> 7.0 -> 7.x to avoid breaking your data.  Just importing 6.x data into 7.x will give you a broken system.

Your downtime is an unavoidable thing.

No.

But with the second method, the users will also get impacted by the intermediate upgrade steps as it would not be possible to change everything over a weekend.

Will it be possible to upgrade the new machine with the 2nd method as you suggested which could take at least  1 week. Now we just bring all the ticket data from old v6 machine on to new v7.7 machine, is this possible?

This way users will not face any lag in their data.
