I have a nextcloud box installation, and I’d like to use instead nextcloudpi since this project appear to be better maintained.
I have no clue where to start, beside @nachoparker’s website, which do contain some installation procedure, but I did not find how to handle existing data from the nextcloud box.
Could someone let me know a step by step procedure with the specificity of the nextcloud box installation, so I don’t lose my data ?
I have a Raspberry 2 with nextcloud version 11.0.5.
Thanks for your answer. I actually need a bit more help to start, but I’d be happy to document what I’ll learn.
copy my data to a PC: ok
Well, almost, the reason is that it’s just to have a backup of the data, in case of something goes wrong ?
export calendars, etc… ok.
Same ?
install and configure NCP: not ok.
I guess I need to install with option 1: Run from SD card, right ?
What do I do with the SD card that I got from the nextcloud box ? Shall I buy another one or can I erase the nextcloud box stuff, or it’s better to keep that one, in case of failure ? Other option ?
What do I do with the hard drive provided with the nextcloudbox ? I just let it as such and nextcloudpi will find the data back at the end ?
Sorry for the many “basic” questions, but I don’t really feel confident trying stuff I just guess based on general how-to.
You can reuse it for sure. You might want to make a copy in your PC, but it is not necessary.
NCP will detect the hard drive, and I recommend that you format it (from NCP menu). In that step, all its contents will be erased (therefore the copy). Then, you can put your data back in again.
Ok, I can make a copy of the entire SD card in case I want to switch back to the snappy installation right ? Will the command sudo dd bs=4M if=NextCloudPi_XX-XX-XX.img of=/dev/sdx erase the card and replace it with the img ? Or it will just copy the img ? How the the Raspberry will know to boot from this image ? Is it because of the /dev/ location ?
In case it just copy, will the ssh config file will be the same and I’ll be able to connect with my former password, won’t I ?
Copy all data from the WD hard drive to my computer
Remove SD card foom NCBox and plug it in you computer
Copy the content of it in case it goes wrong (Actually I’m not sure if I did it correctly since there are different partitions in it and I just copy the content of what was available in Finder, I think only the boot partition).
flash it with sudo dd bs=4m if=NextCloudPi_12-04-17.img of=/dev/disk4 (not bs=4M on mac)
run the command sync
unplug and replug the SDcard
cd /Volumes/
touch ssh
eject the SD card
insert it in the raspberrypi
start
go to nextcloudpi.local
Remove the former ssh key from known host in .ssh/known_host in your home computer.
ssh pi@<ip>
password: raspberry (not raspbian)
Type passwd to change the ssh password
So far so good, but I still have some issues:
I have a nextcloud instance working, but I’m not really sure how to recover my data, since there are still on the HD, and running the format USB drive from the ncp wizard, did not work (don’t recall the error). But then, since I still have the data on the drive, isn’t it easier to move them at the correct position ?

Then I thought, well, let’s go for freeDNS. So I register there, but then, I don’t know whether I should create a subdomain, a domain, or anything else, and where to click and so on… Any help would be appreciated !
thanks for writing down the steps for others… keep it up!
regarding letsencrypt… probably your ports are not correctly forwarded. NCP tries to do this automatically but it does not always work (as explained in the wizard).
I suggest you paste here the output of nc-info (in ncp-web, or nextcloudpi-config). It will detect if your ports are open, otherwise if autoforward doesn’t work you will have to do it manually (see wiki).
In some (sad) cases your ISP will block some ports, or you will be behind a cg-nat. Nothing we can do about that other than changing ISPs, but in many cases you can contact them and have it fixed for you.
regarding the USB drive… I would be interested in seeing why it fails… if you could paste the output it would be helpful. Remember that formating will remove all data on the drive, so you should have the data on your PC or somewhere else.
after formatting, and moving the datadir, you could either
re-upload (sync or NC web interface), or
shutdown pi, plug USB into desktop, copy files over, replug, turn on pi, run nc-scan for NC to recognize the new files.
For let’s encrypt, it used to work, and at one point they changed something on their side and it did not work for me anymore.
Here is the log of nc-info:

You should enable dnsmasq to use your domain inside home
You should run Lets Encrypt for trusted encrypted access
You should use nc-datadir to move your files to your plugged in USB drive [Jean: done in the wizard afterward]
I’ve redone the usb drive wizard and it worked this time (it’s empty now). Note that in the WebUI, nc-datadir is not ticked while nc-automount is. Where can I get the name of the mounted HD ? And how can I be sure that’s everything is ok ?
I also have a small issue with the accounts. How can I rename the admin account ? Also, I have disabled one but can’t enable it again (it disappeared).
your ports seem to be open… can you access from outside, even if you get untrusted certificate warning?
the problem you are facing is a connectivity one. if you are positive that port forwarding configuration is correct (that’s what it seems), contact your ISP, maybe they changed something.
Ok, but reloading the page doesn’t change anything. What mechanism trigger the reconnection ?
So far I log out from nextcloud and log in back, reload the window, click on shutdown (what does it shut down ?) close the window, open another, and it eventually work again.
Well, of course the Nextcloud web has far more work put into it than the nextcloudpi web, which is very basic.
Depending on your browser you might have to refresh without cache ( ctrl+F5 ), or open the URL in a new tab to force actually asking the web server for a new page.
That’s on the list to be improved, but not very high priority
You can open an issue on github if you want to track it and know when it gets fixed.
