Dear Gent, PiraeusN, Karlskrona,
I remind you the link to the survey answers:
https://docs.google.com/spreadsheets/d/1DtFxLJWmeMZqui0gIIyswdbEH7fnb2icRKAI5cRAlbQ/edit#gid=1189530417

At this time:


  *   4 Users ask for migrate resources from Gent
  *   3 Users ask for migrate resources from Karlskrona
  *   14 Users ask for migrate resources from PiraeusN

If you didn’t received it, this is the letter I sent to all FIWARE Lab users (you can use it as template to contact your own list):

I see that Fanis from PiraeusN, is already working on the migration, please also Gent and Karlskrona to give me a feedback about the operations.

Thanks,
Alfonso

Dear Alfonso,
do you have any "template" email we can send to our users for the discontinuation of our node?
Fernando's script has worked and we have all our users email addresses so we can contact them.

Regards,
Fanis

Dear Fanis,
as far as i know and remember from XIFI, there isn't an automatic process to migrate resources.
You should "simply" do a snapshot of your VMs/Disks, contact the destination node, and pass them such files.
But please Fernando and all of you who already faced the migration, to correct me if I'm wrong, and/or add further useful information.

Thanks!
Alfonso

Dear Gent, Karlskrona, PiraeusN,
I see from the answers table that 8 users already replied the survey:

https://docs.google.com/spreadsheets/d/1DtFxLJWmeMZqui0gIIyswdbEH7fnb2icRKAI5cRAlbQ/edit?usp=sharing

Please go ahead thus we can speed up the end of the migration…

Kind regards,

Recap and next steps after today’s call.

According to list [1], nodes that will not continue with us beyond
February 2016, are:

 * *Gent*
 * *Karlskrona*
 * *PiraeusN*


(See list [1] for more details about the amount of resources present
on those nodes)

I'm going to send an email to all FIWARE Lab users in order to inform
them about the re-organisation of FIWARE Lab and introducing them the
survey [2].
This is for transparency toward the consortium and all users.
It basically means, that I'm going to send this email, but _Gent,
Karlskrona and PiraeusN, will send the email to the specific list of
their users as well,_ in order to have a direct dialog with them and
to organize the migration of resources.

The plan is to inform users affected by the migration within
tomorrow, give them the time to reply the survey within Monday 22nd
at 08:00, then start the migration, and finalize the migration within
Friday 26th.

In details:

1. [02/16] —> Fernando is going to finalize the script for retrieve
   users list from a specific node.
2. [02/16 - 02/22] —> Please all of you who have already faced the
   migration of resources at the end of XIFI, to share useful
   information/documentation among all other nodes in order to be
   ready Monday 22nd with the new migration process.
3. [02/17] —> Thanks to Fernando' script, Gent, Karlskrona and
   PiraeusN will inform their specific users list about the
   migration (you would use the email I’m going to send to all
   FIWARE Lab users as template for yours ). Please cc me.
4. [02/19] —> Gent, Karlskrona and PiraeusN will send a reminder to
   their specific users list. Please cc me.
5. [02/22] —> Double check survey answers [3] and start the
   migration. (if some users reply before the deadline, you can
   start earlier...)
6. [02/26] —> Finalize the migration.

As you may notice, unfortunately we have very few time in order to
complete all the operations, I kindly ask you an extra effort and
collaboration in the coming days...

Thank you in advance and don’t hesitate to contact me for any doubt!

Kind regards,
Alfonso

Dear all,
since most of you have already received results from the Open Call,
it’s time to think about migration plan for those nodes who will be
discontinued.

Next steps will be:

1) Collect information about intention and amount of resources to
migrate [_Deadline Monday 15th EOB_]

In order to that, please fill in the following document
[https://goo.gl/d6RUkK]

Guideline:
- column B: please answer YES/NO and till when.
- column I,J: please answer after the results of the survey we will
send next Tuesday (see step 2).

2) Send a survey to Community Users (for those nodes who will be
discontinued only) asking if they required support to migrate to
another node.

I will share with you the survey Tuesday 16th during our weekly
phone call.

3) After step1 and step2, each discontinued node will be in charge
to assess the tenants to be migrated and co-ordinate with the
destination node for the support to migration.

note:
(I know that some of you are not be able to offer support beyond
this month, so if you collect the information before the deadline we
can move forward and proceed in advance)


Thanks for the cooperation!
Alfonso
