[jean houssin]

Hello, I want to migrate the version of JIRA 6.3.7 to version 8.2. Can you explain to me the procedure to apply? I can not find the answers. Thanks

Hi,

if you re not so fimiliar with those types of upgrade I recommend you contact any Atlassian Solution Partner company in your country.

It needed several interim versions and probably a lot of manual steps.

Be careful regarding checklist

If you will choose installer method follow this

I can recommend you go through this way:

6.3.7 -> 6.4.14 -> 7.0.11 -> 7.13.3 -> 8.2.1

[jean houssin]

thank you very much for that !!  that helps a lot. Do you have a idea of a planning ?

[Petr Vaníček]

What you mean with planning?

[jean houssin]

I would like to make a provisional schedule for this migration but I do not know how long it takes for this

[Petr Vaníček]

First do this on test environment - then you will know what problem you can expect on production and how much time it will take.

Based on my experience - if you don't have any special add-ons and customizations - it could take on production whole weekend (better start at Friday afternoon after bussiness hours).

[jean houssin]

ok I understand better. So the weekend would be enough to migrate to version 8.2.1 ?

[Petr Vaníček]

If there will not be any serious problem - then yes.

Hello @jean houssin - I encourage you to heed these very wise words from @Petr Vaníček - "First do this on test environment - then you will know what problem you can expect". 

This is not a trivial change you are making.  You will likely need to work out problems in your test environment (which should be a copy of your production environment, not a vanilla installation) at several stages.  Practices this until it is a well-documented and smooth operation.  Then you will be better prepared with a comprehensive plan, fairly accurate time estimates, and be able to focus more on the unexpected things that will happen during your production outage.
